摘要:
A nonlinear rate-measuring instrument. A multivibrator controls the generation of fixed-amplitude current pulses at a rate equal to that of an input signal whose rate is to be measured. The pulses are averaged and the output voltage is a function of the input rate. This generally linear type of operation is made nonlinear by using the output voltage to control the period of the multivibrator, i.e., the width of each generated current pulse. High-scale or low-scale compression can be achieved depending on whether the output signal is used to decrease or increase the multivibrator period.
