Control circuit

摘要

A signal conditioning circuit for a servo signal derived from a magnetic record tape includes a frequency selective signal normalizing circuit which normalizes the reproduced signal to a predetermined value irrespective of the frequency of the input signal. The selective operation of the normalizing circuit is programmed in accordance with a digital code signal representative of the selected speed of operation. A frequency selective filter circuit is also programmed in accordance with digital code representative of the selected speed of operation.
