IPC: H04L27/14
Filed: 1990-10-16
Abstract: PURPOSE:To attain excellent reception even when a received signal is weak by using a signal added by a signal adder so as to demodulate a binary digital signal thereby improving the S/N. CONSTITUTION:Switch circuits 2a, 2b, 3a, 3b, 4a, 4b of a non-delay circuit 2, a delay circuit 3 and an adder circuit 4 in a signal adder circuit are switched in a prescribed consecutive timing. That is, they are switched at a period of Td/N as one cycle (Td is one period of a base band signal and N is a period of a sampling period or over). As a result, a charge corresponding to a signal voltage at an input terminal 1 is charged in a capacitor 2c for the 1st half in the period Td/N and the charged charge is discharged to the output side for the latter half to send a signal delayed by a time Td/2N. Since the power of the base band signal voltage is doubled and the voltage is only a multiple of 2<1/2>, the S/N is improved by, e.g. 3dB.

Abstract: PURPOSE:To obtain an actual value having an amplitude coincident to the primary current command value even when the gain of a regulator drops by using the value produced by adding a compensating value to a command value as an amplitude command value of a current regulator.
