As a technology, analog is the process of taking an audio or video snal (the human voice) and translating it into electronic pulses. Electronics work on DC and with a voltage range of -48v DC to 48v DC. Electric devices use line voltage (120v AC, 240v AC, etc…). It states that, while taking the samples of a continuous snal, 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. To avoid confusion, people could take turns speaking (time division), speak at different pitches (frequency division), or speak in different directions (spatial division). People speaking the same language can understand each other, but not other people.

Communication means transferring a snal from the transmitter which passes through a medium then the output is obtained at the receiver. Dital snals are immune to noise, quality of transmission and reception is good, components used in dital communication can be produced with hh precision and power consumption is also very less when compared with analog snals. Examples: are incandescent lhts, heaters, fridge, stove, etc… Many codes occupy the same channel, but only users associated with a particular code can understand each other. The basic difference lies in the Multiplexing method used in the aerial communication i.e. CDMA uses Code Division Multiple Access as the name itself indicates, for example you are in a hall occupied with number of people speaking different language. Diodes have two active electrodes between which the snal of interest may flow, and most are used for their unidirectional current property. The transistor is the fundamental building block of computers, and all other modernelectronic devices. An operational amplifier, often ed an op-amp , is a DC-coupledhh-gain electronic voltage amplifier with differential inputs and, usually, a single output. The frequency at which the response is -3d B with respect to the maximum response. The impedance curve of an R-L-C network cuts the frequency axis only when the frequency is such that (a) XL=XC (b) XL=XC=0 (c) R=0 and XL=XC (d) none of these 2.

Dital on the other hand is breaking the snal into a format where the audio or video data is represented by a series of “1”s and “0”s. 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 economiy the materials and forces of nature for the benefit of mankind. 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. Electric devices can also be desned to operate on DC sources, but will be at DC voltages above 48v. The process of obtaining a set of samples from a continuous function of time x(t) is referred to as sampling. Similarly, in radio CDMA, each of users is given a shared code. These are the two different means of mobile communication being presently used worldwide. In electronics, a transistor is a semiconductor device commonly used to amplify or switch electronic snals.

The study and use of electrical devices that operate by controlling the flow of electrons or other electriy charged particles. (or)communication says as transferring of message from one place to another place ed communication. You will find that the one language you know will be heard by you and the others will be treated like noise. Feedback is a process whereby some proportion of the output snal of a system is passed (fed back) to the input. A semiconductor is a solid material that has electrical conductivityin between that of a conductor and that of an insulator(An Insulator is a material that resists the flow of electric current. Some transistors are packaged individually but most are found in integrated circuits. Typiy the output of the op-amp is controlled either by negative feedback, which largely determines the magnitude of its output voltage gain, or by positive feedback, which facilitates regenerative gain and oscillation. In a semiconductor diode, P-side is grounded and N-side is applied a potential of -5V through a resistance of 100 ohms.
