Abstract

PURPOSE: To standardize a circuit substrate, etc., and also to improve various characteristics by deriving a fixed constant intermediate frequency at any time even if an index frequency would vary due to a static or dynamic variation factor.
CONSTITUTION: Tuner part 10 consists of photo detector 11, voltage control filter 12, mixer 13, local oscillator 14, and variable resistor 15 for local oscillation frequency setting. 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 14 are mixed by mixer 13 to obtain intermediate frequency (fi), which is supplied to intermediate frequency 20; and filter 21 removes a signal component of an unneeded frequency and the remainder is supplied to mixer 30. Here, (fi) and (fl) are mixed and to its output side, a frequency equal to index frequency (fi) from detector 11 is derived.
