Abstract
A circuit for converting an input signal with an arbitrary duty cycle to an output signal with a 50 percent duty cycle. A bandpass filter removes unwanted DC and high frequency components from the input signal. A comparator compares the filtered signal to a reference voltage and provides very high gain amplification to produce an output signal having a 50 percent duty cycle. In one embodiment, two bandpass filters are used to condition the signal prior to providing it to the comparator. Each bandpass stage is comprised of a low pass filter followed by a high pass filter.
