FREQUENCY PROPERTIES OF A LOCKED-IN ACTIVE OSCILLATOR WITH AUTOMATIC OSCILLATING-FREQUENCY TUNING

摘要

A comparative analysis of frequency properties of a locked-in active oscillator has been made from one or two control inputs, one of which affording automatic oscillating frequency tuning. It is shown analytically that the key advantages of the oscillator already examined when it is used as a Doppler filter. A follow-up Doppler can be implemented whose function circuit differs from the circuit arrangement of automatic frequency or phasecontrol.
