Amplifiers are the device which are used to amplify a signal Multistage amplifier are use to amplify a signal into a desire level
to amplify a small signal to sufficient level,so that it can travel to a large distance from first stage till the last stage
Advantages of multistage sampling?
the combinitoin of any random samples is called multistage samplinag.
it is the expensive form of cluster samling. when each elements in cluster are expensive then we use multistage sampling.
