1. OBJECTIVE To study the behaviour of a linear amplifier. 2. INTRODUCTION An amplifier is an instrument which is capable of amplifying every component in a signal by the same amount. For a linear amplifier, the output signal is an amplified version of the input signal, which is given by V out = + A Vin where A is the gain of the amplifier. In an ideal amplifier, the gain A should be constant over a range of conditions. However, in practice, the gain may change as the amplitude and frequency of the input signal varies. To avoid distortion in the output signal, the input signal must be restricted to a certain range of amplitude and frequency values. The gain, A, is a function of frequency. The variation of A with frequency of a typical amplifier, shown by
