Abstract

PURPOSE: To standardize a circuit substrate, etc., and also to improve various characteristics by deriving a constant frequency all the time even if an index frequency and inch size of a picture tube would change.
CONSTITUTION: Tuner part 10 consists of photo detector 11, mixer 12, local oscillator 13, and variable resistor 14 for local oscillation frequency setting. Intermediate frequency part 20 consists of intermediate-frequency band-pass filter 21 and limiter amplifier 22. 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 amplifier 22 suppresses an AM component, only a signal component of (fI) is supplied to mixer 30. Then, mixer 30 mixes (fI) and (fl) and to its output side, a frequency equal to index frequency (fi) from detector 11 is derived.
