Q. Explain the different coupling schemes used in amplifiers?
When amplifiers are cascaded, it is necessary to use a coupling network between the output of one amplifier and the input of the following amplifier. This type of coupling is called inter stage coupling. Basically these coupling networks serve the following two purposes.
1. it transfers the a.c. output of one stage to the input of the next stage.
2. it isolates the d.c conditions of one stage to the next.
