Frequency multiplexer for ultrasonic Doppler blood flow signals.

F J Thomson1.   

Abstract

An instrument is described which uses single-sideband techniques to combine two channels of Doppler flow signals into a form suitable for simultaneous processing by a single-channel real-time spectral analyzer. The maximum input frequency range is 50 Hz to 10 kHz.
