Title: Tracking error detecting circuit
Inventor: TOYONAGA KENJI
IPC: G11B15/467
Filed: 1985-02-20
Abstract: PURPOSE:To make possible quick tracking control by providing a window processing circuit having an attenuation control means which varies gradually the attenuation of attenuating means from max. to 0 at the beginning end of synchronous addition and varies gradually the same from 0 to the max. at the terminal end of the synchronous addition. CONSTITUTION:The window processing circuit 18 is the circuit which multiplies the window signal of a staircase waveform by a digital signal Aij, i.e., the circuit which makes window time processing by multiplying the load function along the time axis by the original waveform in order to make both ends of a cut-out section such as Hamming window, Hanning window or gauss window gradually to 0 without inducing an abrupt change. The frequency characteristics of both synchronous adder circuits 6, 7 in a synchronous addition part 5 are decreased in the level of upper and lower side band regions Fs. Therefore even if the synchronous addition of the circuits 6, 7 is executed fewer times, the level of the component based on the signal of the main band, i.e., the level of the pilot signal component to be extracted is substantially higher than the level of the noise component based on the signal of the side band region Fs and the time required for the synchronous addition of the part 5 is reduced.
