Differential sampling circuit for improving signal to noise ratio in an electronic organ having multiplexed keying |
摘要 |
The present invention is a differential sampling circuit for improving the signal to noise ratio by eliminating d.c. level distortion in square wave signals used as components for forming a stairstep or bright wave signal in an electronic organ having multiplexed keying. The multiplexed drawbar signals for even footages at both sides of a sampling resistor are demultiplexed, applied to a sample and hold circuit and applied as inputs to a differential amplifier to cancel any fluctuations of the d.c. signal component.
