9.1 Characterization of Channel Distortion

 

Many communication channels, including telephone channels and some radio channels, may be generally characterized as band-limited linear filters. Consequently, such channels are described by their frequency response C(f), which may be expressed as

$$C(f)=A(f)e^{j\theta (f)}\left(9.1\right)$$

where A( f ) is called the amplitude response and θ( f ) is called the phase response. Another characteristic that is sometimes used ...
