Extract of sample

Therefore, practical amplifiers will have finite distortion and minimal noise with which they will invariably add to the said signal (Bishop 98). An exception is given to the cases where the amplifier is a transducer, which means that the amplifier shifts the types of signals from one point to another. Types of Amplifiers The mainstay of any electronic circuit will certainly be the amplifier (Bishop 18). Classification of amplifiers is broad, but the best way in which amplifiers can be classified is in relation to the input and output of each amplifier. In order for the amplifier to have some gain, it means that the scale of the input and output signal to the amplifier will have some degree of variation. The definition of it can be summarized as the quotient of three aspects, i.e., the power, the current and also the voltage. Furthermore, the gain will also be in terms of the output or the input signals of either the voltage or the power in any amplifier (Satyam and Ramkumar 32). In cases where the gain is undefined, it implies that the input and the output signals in an amplifier are almost the same in terms of unit signals; thus, in most cases a good example will be the decibel which has the same format described. ...Show more


instructor Amplifiers Introduction An amplifier can be described as a device that is used to increase the power of any signal through the use of an external source of energy (York 12). There are various types of amplifiers that can be found today with different purposes…
