  • Transient error reduction for stored charged circuits
    Patent number: 4437067
    Abstract: A stored charge circuit having a transient error such as a ringing or the ke in response to a step function or other transient error initiating input signal is presented. Normally open switches are connected across at least some of the resistors of the circuit and are closed for an interval of time upon the occurrence of a transient error thereby changing the transient error.

  • Doppler signal processing circuit
    Patent number: 4333079
    Abstract: A signal processing circuit for producing a warhead firing pulse when the rhead is in a position to cause maximum target damage in a missile, target encounter. The received doppler signal is processed through filter circuits and a first band-pass amplifier. A second band-pass amplifier tuned to pass a narrow portion of the frequency spectrum above the doppler signal is connected in parallel with the first amplifier and its output signal is used to vary the threshold bias to compensate for the presence of extremely noisy signals.
