Title: Arrangement of circuit for generating output signal
Inventor: SCHILLHOF UDO
IPC: H04R3/12
Filed: 1999-11-09
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of distortion by switching controllable switches at a duty cycle to be complementarily and gradually changed between mutually opposite states of a completely conductive state and a completely blocked state. SOLUTION: A common node 11 is switched from one of input terminals 2, 3 to the other and a signal from the node 11 is switched from one input signal to the other by complementarily and gradually switching the controllable switches 9, 10. At the time of receiving a control signal having a high logical level L, the switches 9, 10 are closed, and at the time of receiving a control signal having a low logical level H, the switches 9, 10 are opened. Since no action is executed in the center area of the characteristics of the two switches 9, 10 in the two states for obtaining an output signal from input signals supplied through the switches 9, 10, it is impossible for insufficient complementary matching in the center area to exert influence upon the operation of circuit arrangement.
