Passband transmission model

A band-pass filter can be characterized by its Q factor. The Q-factor is the reciprocal of the fractional bandwidth. A high-Q filter will have a narrow passband and a low-Q filter will have a wide passband. These are respectively referred to as narrow-band and wide-band filters. Web9 Sep 2024 · Passband transmission. Multiplexing Techniques. Sharing of a transmission channel by various signals is called multiplexing. The different multiplexing techniques are as follows −.
