Abstract
PURPOSE: To standardize a circuit substrate and also to improve various characteristics by deriving an invariably-constant intermediate frequency even if an index frequency would vary due to a static or dynamic variation factor.
CONSTITUTION: Tuner part 10 consists of photo detector 11, mixer 12, local oscillator 13, and local-oscillation-frequency setting variable resistor 14. Intermediate frequency part 20 consists of intermediate-frequency band-pass filter 21, limiter amplifier 22, FM detector 23, and low-pass filter 24. Then, index frequency (fi) from detector 11 and local oscillation frequency (fl) from oscillator 13 are mixed by mixer 12 to obtain intermediate frequency (fI), which is supplied to intermediate frequency part 20, and after filter 21 removes a signal component of an unneeded frequency and limiter amplifier 22 suppresses an AM component, only a signal component of (fI) is supplied to mixer 30. Here, (fI) and (fl) are mixed and to its output side, a frequency equal to frequency (fi) from the detector is derived. Further, filter 24 sends its output to a polarizing method for scanning-rate modulation.
