Instantaneous frequency meter with averaging capability based on interval duration measurement

K Schmid et al. Electroencephalogr Clin Neurophysiol. 1985 Jan.

Abstract

The instantaneous frequency meter described uses an inexpensive hybrid module for on-line interval to frequency conversion and also has a digital low pass filter function. The device is not only a frequency to voltage converter but also is well suited to serve as an interface to a digital computer.
