Abstract
A method and system for converting an input signal into a dynamically-controlled digital output signal. A sensitivity and a threshold level of a digital input signal is adjusted. An absolute value or a constant polarity of the adjusted digital input signal is compared to a previous output signal and at least one state variable is modified to achieve a desired attack time of the filter. The adjusted digital signal is either then passed through or bypassed around the filter to produce the dynanically-controlled digital output signal.
