Transient Response of Asymmetrical Carrier Systems

The transient properties of asymmetrical amplitude-modulated carrier systems are studied in the time domain. A vector integral method is given for the determination of system response to arbitrary modulation. Typical nonlinearity of the envelope transfer function is studied as a function of modulation depth. It is found that the time delay associated with a rising response to a step change is always less than the delay associated with a decreasing response to a similar change. Transient improvement as a consequence of detuning in asymmetrical systems appears to be accompanied by a decrease in signalto-noise ratio.
