Frequency Conversion and Limiter Action for an Angle-Modulated Wave With Amplitude Fluctuation in a Half-Wave Linear Mixer

Signal interaction is analyzed when the composite signal of a simultaneously amplitude- and angle-modulated wave, a nonmodulated sinusoidal wave, and a noise is added to a half-wave linear mixer. If a certain mixing condition is satisfied, a half-wave linear mixer operates like an ideal bandpass limiter with frequency conversion function. The limiter action is also verified by experiment.
