Single-channel pulse height discrimination circuit by means of dual monostable multivibrator

By analyzing time sequence of outputs of upper and lower discriminators, a simple, effective and practical method is presented, in which single-channel pulse height discrimination circuit is implemented by means of dual monostable multivibrator,and actual circuit is built to solve complicated circuit of common single-channel pulse height analyzer. Actual working waves show that the novel method is feasible and test circuit works properly and reliably as the input signal frequency increase up to 400 kHz, sine wave or exponent falling. It may be applied to pulse height discrimination in nuclear radiation energy measurement. (authors)
