WebMulti-Stage Transistor Amplifier. In practical applications, the output of a single state amplifier is usually insufficient, though it is a voltage or power amplifier. Hence they are replaced by Multi-stage transistor amplifiers. In Multi-stage amplifiers, the output of first stage is coupled to the input of next stage using a coupling device. WebThe basic purpose of a coupling is to permanently connect two shafts. Shafts in power transmission are not always linear connections; They can be parallel, with intersecting axes and slight eccentricity. Therefore a different type …
WebThe function of a power amplifier is to raise the power level of input signal. It is required to deliver a large amount of power and has to handle large current.
