AbstractThe introduction of a phase/frequency-locked loop (PFLL) technique made the task of transmitting information with a high degree of accuracy less cumbersome. The PFLL became possible after a high precision, continuous type phase/frequency-to-voltage converter/demodulator (PFVCD) was developed. It performance at a wide frequency band (DC-80 KHz), dynamic range up to 120 dB, and precision pulse width discrimination has made possible to build fast hopping PFLL based coherent timemultiplex PM-PM system with only few tenths of a degree of radians spacing between channels. A parallel type decoder was built to demodulate and separate individual channels. It employed the PFVCD which n-shape (ideal) bandpass characteristic and high level linearity eliminates crosstalk and minimizes distortion of an original signal.
