Title: Full-wave rectifying circuit
Inventor: UENO NORIO
IPC: H04L7/027
Filed: 1984-05-16
Abstract: PURPOSE:To stop a full-wave rectification output signal to prevent disturbance by detecting a continuous rectification output signal if a signal containing echo components is inputted. CONSTITUTION:The input signal is applied from an input terminal IN to an operational amplifier OP1 through a comparator CMP1, a switch circuit SW1, and a resistance R3. The inverted output signal of the amplifier OP1 is applied to a switch circuit SW2 and a comparator CMP2, and comparators CMP1 and CMP2 compare these signals with a reference voltage from a terminal B. Since ''1'' is outputted if the signal eceeds the reference voltage, the output signal of an NOR circuit G4 becomes ''0'', and a flip flop FF1 is reset; and when a flip flop FF2 is reset also after a half period of a clock signal, a switch circuit SW3 is turned on. Consequently, when signals S1 and S2 are inputted, the latter signal S2 is stopped because switch circuits SW1 and SW2 are turned off.
