Abstract : The patent describes a band-pass pulse width filter for filtering a sequence of positive going digital pulses. A first pulse width filter having four two-stage logic circuits blocks pulses having a width lesser than a first predetermined width and provides an output for all other pulses. A second pulse width filter having four two-stage logic circuits has an input coupled to the output of said first pulse width filter and blocks pulses having a width greater than a second predetermined width. The output of the second pulse width filter consists of positive going digital pulses having a width greater than said first predetermined width and a width lesser than said second predetermined width.
