Design and simulation of the basic components of an analog communication system using MATLAB programming. Specifically, an AM modulator and a corresponding super-heterodyne receiver are simulated using radio-station generated signals.Receivers need a lot of gain, and mixers are usually the limiting factor in high dynamic range. So you'd like to put all of your gain after the first mixer, which tends to be the one that sees the most interfering signals. For a sensitive SSB receiver this gain can be in excess of 120dB. It is difficult to impossible to get that much gain ...super-heterodyne receiver for appropriate selectivity [2], the homodyne requires less number of external components. However, the homodyne architecture does suffer from a number of implementation issues.
