ABSTRACT:
In a tuning circuit the reception frequency is measured by counting the oscillations of the heterodyne oscillator, taking the intermediate frequency into account. The result of measurement is compared with a selected value. The tuning operation is controlled in accordance with the result of comparison and further in accordance with the tuning voltage in a manner to reduce non-linearities in the rate of tuning controlled by the tuning voltage.
