The effect of the oscillating limiter on message modulation when its bandpass filter has a flat amplitude and linear phase characteristic in the frequency range occupied by the input signal is discussed. A baseband equivalent transfer function of the oscillating limiter is introduced. When the linear model does not apply, the dependence of the distortion of the output message modulation on the amount of feedback, group delay around the loop, and characteristics of the input signal is shown through a series of curves. Results of this analysis give basic data for the design of an oscillating limiter, once the modulation Characteristics of its input signals have been specified. |
