I want to know what a sample and hold circit is, how it works and how it can be simulated(on which software) and implemented practically in lab useful for communication systems. Also the different components required with specifications required. Plz help..

Take a look at this.

It can be simulated best with a SPICE simulator program. A free version that many forum members use is LTspice from Linear Technology.

The sample-and -hold circuit specifications are determined by the application requirements (sample acquisition time, sample hold time, sample accuracy, etc.) which you have not stated.

Depending upon the requirements it can be implemented with discrete analog switches and op amps, or a dedicated S&H IC.
