Abstract
A monopulse pulse width discriminator for differentiating between input sals on the basis of pulse width and amplitude, having discriminator and timing circuits which outputs gate a video track loop fed by the modified input signal.
Claims6
An electronic system for differentiating between signals on the basis of pulse width and amplitude, comprising:
- input means adapted to receive an input signal;
- a logarithmic amplifier operatively connected to said input means and providing an output;
- discriminator means operatively connected to the output of said logarithmic amplifier for discerning the pulse width of said input signal relative to a reference, and for providing outputs from a first and second coupler wherein said first coupler provides an output only when the pulse width of said input signal is greater than said reference;
- timing means also operatively connected to the output of said logarithmic amplifier for providing timed signal outputs;
- gating means operatively connected to said first coupler and said timing means for providing a signal output only when signals are simultaneously received from said first coupler and said timing means;
- and
- a video track loop operatively connected to said second coupler and the output of said gating means, and providing the system output.
