Abstract

By providing a coupling circuit with two different time constants, unwanted large noise signals can be drastically attenuated. Small data signals which follow the noise signals are permitted to pass through with little attenuation. With transistors T1 and T2 conducting, the coupling circuit provides a very short time constant to attenuate the noise from amplifier 10. When transistors T1 and T2 are rendered nonconductive, the coupling circuit provides a longer time constant. This action permits small signals to pass through transformer 12 with little attenuation.
