Diode & Filter Applications in Amplitude Modulation (AM) Detection Circuits
The operation of a typical AM audio frequency signal is illustrated in the Figure 1.0 where vin is the modulated signal that is shown Figure 1.1. A typical amplitude modulated signal that is fed into the detector circuit: The diode removes the lower envelope and the upper envelope is illustrated below: The capacitor C2 and…

Applications of Filters in Telecommunication Systems
Electronic filters have many applications in the telecommunication and data communications industry. For example, they are used in a multichannel communication system employing a technique known as time-division multiplexing (TDM). In this system, several channels are transmitted through a medium such as optical fiber or through a co-axial cable or waveguide. Multiplexing means combining several…
