Abstract:

A continuous wave phasemeter was designed with the capability to operate with short duration pulses of continuous wave signals pulsed cw in a background of noise. An exclusive-OR gate provides the phase detection between the input signal and a reference signal. Sample and hold devices are used to provide the capability of averaging phase fluctuations from one pulse to another. The unique concept of quadrature phase logic is implemented in achieving truly linear transfer curve even with the presence of noise in the input signal. Keywords include Amplitude and phase measurements Phasemeter Sample and hold Programmable amplifier Pulsed cw operation and Quadrature phase.
