ABSTRACT:
A method and apparatus is disclosed which improves the image quality obtained in a system for displaying frequency demodulated acoustic images of an object. A squelch signal is added to the input of a frequency demodulator. When the "echo signal" represents merely high frequency noise input to the demodulator, the squelch signal overrides the noise. A uniform level is thereby provided to the image display devices of the system which substantially improves output image quality.
