ABSTRACT:
Herein disclosed is a pulse width decoder comprising an oscillator activated to generate clock pulses of relatively short duration as long as an input signal pulse is applied, a shift register adapted to channelize a multiplicity of pulse widths, means including a divider counter for utilizing locally generated pulses to shift the register, and means including feedback circuitry from the shift register to the divider counter to change the divisor in the counter so that the range of window tolerance provided by the channelizing is effectively increased, in steps, with ascending groups of pulse widths. Additionally, delay means is incorporated to provide for a minimum limit of acceptable input signal pulse width.
