Adaptive decoder for skin effect limited signals
The present invention is a decoder for decoding a signal. The decoder includes a discriminator and a threshold generator. The discriminator receives the signal and generates an output voltage equal to a first voltage if the signal is less than a threshold level that is input to the discriminator and equal to a second voltage if the signal is greater than the threshold level. The threshold level depends on the output from the discriminator in a preceding time interval that depends on the impulse response of a transmission link through which the input signal has passed. The threshold generator implements a low-pass analog filter that receives the output voltage during each of the clock periods and generates therefrom a filtered output signal.
