    3 - 2 the detected voltage is also applied to the noise blanker agc circuit (q12, q10) and is then fed back to the noise amplifier (ic8) as a bias voltage. The noise agc circuit prevents closure of the noise blanker gate for long periods by non-pulse-type noise. The time constant of the noise blanke...
