Digital signals are immune to noise, quality of transmission and reception is good, components used in digital communication can be produced with high precision and power consumption is also very less when compared with analog signals. Define What is engineering The application of science to the needs of humanity and a profession in which a knowledge of the mathematical and natural sciences gained by study, experience, and practice is applied with judgment to develop ways to use economically the materials and forces of nature for the benefit of mankind. Difference between electronic and electrical. Electronics work on DC and with a voltage range of 4. DC to 4. 8v. DC. If the electronic device is plugged into a standard wall outlet, there will be a transformer inside which will convert the AC voltage you are supplying to the required DC voltage needed by the device. Examples Computer, radio, T. V, etcElectric devices use line voltage 1. AC, 2. 40v. AC, etc. Electric devices can also be designed to operate on DC sources, but will be at DC voltages above 4. Examples are incandescent lights, heaters, fridge, stove, etc7. What is sampling The process of obtaining a set of samples from a continuous function of time xt is referred to as sampling. State sampling theorem. It states that, while taking the samples of a continuous signal, it has to be taken care that the sampling rate is equal to or greater than twice the cut off frequency and the minimum sampling rate is known as the Nyquist rate. What is pass band Passband is the range of frequencies or wavelengths that can pass through a filter without being attenuated. What is stop band A stopband is a band of frequencies, between specified limits, in which a circuit, such as a filter or telephone circuit, does not let signals through, or the attenuation is above the required stopband attenuation level. Difference between mobile and a cell phone. Interview Questions And Answers For Freshers In Computer Science Pdf' title='Interview Questions And Answers For Freshers In Computer Science Pdf' />There is no difference, just language use, which differs from country to country, so in Britain it is called a mobile, and in USA and South Africa and other places a cell phone. Even in Europe the name differs. The Germans call it a handy, which in English has completely another meaning as an adjective, meaning useful. In Italy it is called a telofonino or little phone. C language interview questions solution for freshers beginners placement tricky good pointers answers explanation operators data types arrays structures functions. This difference in British and American English is also evident in many other things we use every day, like lifts and elevators, nappies and diapers, pickups and trucks. The list goes on and on, any student of English has to decide which he or she will use, as the default setting. Explain RF Radio frequency RF is a frequency or rate of oscillation within the range of about 3 Hz to 3. GHz. This range corresponds to frequency of alternating current electrical signals used to produce and detect radio waves. Since most of this range is beyond the vibration rate that most mechanical systems can respond to, RF usually refers to oscillations in electrical circuits or electromagnetic radiation. What is modulation And where it is utilizedModulation is the process of varying some characteristic of a periodic wave with an external signals. Radio communication superimposes this information bearing signal onto a carrier signal. These high frequency carrier signals can be transmitted over the air easily and are capable of travelling long distances. The characteristics amplitude, frequency, or phase of the carrier signal are varied in accordance with the information bearing signal. Modulation is utilized to send an information bearing signal over long distances. Define what is demodulation Demodulation is the act of removing the modulation from an analog signal to get the original baseband signal back. Demodulating is necessary because the receiver system receives a modulated signal with specific characteristics and it needs to turn it to base band. Name the modulation techniques. For Analog modulationAM, SSB, FM, PM and SMDigital modulationOOK, FSK, ASK, Psk, QAM, MSK, CPM, PPM, TCM, OFDM1. Explain AM and FM. AM Amplitude modulation is a type of modulation where the amplitude of the carrier signal is varied in accordance with the information bearing signal. FM Frequency modulation is a type of modulation where the frequency of the carrier signal is varied in accordance with the information bearing signal. AM and FM AM is used for video signals for example TV. Ranges from 5. 35 to 1. Hz. FM is used for audio signals for example Radio. Ranges from 8. 8 to 1. MHz. 1. 8. How does a mobile work When you talk into a mobile telephone it converts the sound of your voice to radiofrequency energy radio waves. The radio waves are transmitted through the air to a nearby base station. The base station then sends the call through the telephone network until it reaches the person you are calling. When you receive a call on your mobile phone the message travels through the telephone network until it reaches a base station near to you. The base station sends out radio waves, which are detected by your telephone and converted back to speech. Depending on the equipment and the operator, the frequency that each operator utilises is 9. MHz, 1. 80. 0MHz or 2. MHz. The mobile phone network operates on the basis of a series of cells. Each cell requires a radio base station to enable it to function. There are three types of base station and each has a particular purpose The Macrocell is the largest type and provides the main coverage for mobile phone networks. The Microcell is used to improve capacity in areas where demand to make calls is high, such as shopping centres. The Picocell only has a range of a few hundred metres and may be used to boost weak signals within large buildings. Each base station can only cope with a certain number of calls at any one time. So if demand exceeds the capacity of a base station an additional base station is needed. What is a base station Base station is a radio receivertransmitter that serves as the hub of the local wireless network, and may also be the gateway between a wired network and the wireless network. How many satellites are required to cover the earth The life span of the satellite is about 1. What is a repeaterA repeater is an electronic device that receives a signal and retransmits it at a higher level andor higher power, or onto the other side of an obstruction, so that the signal can cover longer distances without degradation. What is attenuation Attenuation is the reduction in amplitude and intensity of a signal. Role specific Audit Interview Questions and Answers. Basic Soldering For Electronics Pace Handbook 44.

Nearly all frauds have been committed by trusted officials or employees. It is interesting to note that frauds have occurred owing to their being trusted. Relation principle relating to transfer of an employee from one job to another should be the inflexible guiding rule. This is an effective safeguard against collusion and is recognized as an important canon of sound organization. Mechanization of the work wherever feasible and practicable should be resorted to, mechanical devices such as cash register, recording time clocks, calculation machines should be introduced. A system of control accounts should elegantly be fitted in the book keeping system. The work should be so arranged that work done by one employee should be properly checked by independent employee. Such continuous and constant checking goods moral control and the errors and the frauds cannot go undetected. Whats are the importance of evaluating an internal audit departmentSignificance of Internal Auditing Internal auditing refers to an assessment activity managed within a corporation as a check to the entity. Its main function is to monitor control within the corporation.
