Information playback apparatus, in-line circuit, and method for implementing in-line circuit on information playback apparatus |
摘要 |
An information playback apparatus comprises an input amplifier to which an RF signal reproduced from an optical disc is input; a high-pass filter to which the output of the input amplifier is input; an AD converter to which the output of the high-pass filter is input; a lag lead filter to which the output of the AD converter is input; and a demodulator for digitally processing the output of the lag lead filter to demodulate it as a binary signal. Thereby, an optical disc playback apparatus that realizes a DVD-RAM playback function at low cost can be realized.
