An exact general formula is derived relating the data obtained from t.a.c-m.c.a. systems to the input signal distribution; it is shown how the latter is modified by the measuring process. A general method of data correction is given, together with important approximations, which evaluates the input signal distribution from the data without any loss of signal. A simple and accurate method of system calibration based only on counting and not requiring the use of calibrated delay lines is also given.
