Filed: 1983-07-09
Abstract: PURPOSE:To simplify the structure of a signal extracting part and at the same time to obtain a general-purpose IC by providing a frequency counting means for transmission power and changing the reactance in accordance with the counted frequency. CONSTITUTION:A matching circuit 9 serves as a reactance circuit network containing three pairs of variable reactance circuits.

Title: Digital demodulation circuit and digital signal processing type demodulation system
Inventor: NAKAMURA SHIGEKI
IPC: H04L27/00
Filed: 1988-05-25
Abstract: PURPOSE:To reduce the effect of jitter due to a timing reproduction system by applying interpolation processing estimating a signal value at an asynchronous timing clock time with respect to a sampling digital signal of a reception signal detected by a reference carrier and operating a timing extraction circuit synchronously with the extracted clock. CONSTITUTION:A sampling frequency of an A/D converter 2 is selected to be a fixed frequency and carrier recovery/detection for the reception signal is applied at the sampling period to obtain a reception detection signal. On the other hand, the processing applying extraction and synchronization of the transmission data timing component from the reception detection signal is a processing synchronizing with the recovered timing. Thus, the sampling frequency by an oscillator 5 and the extracted recovery clock 8 are independent. Consequently, jitter caused by a recovery clock operating section 11 gives no effect in the sampling operation section 10.
