Abstract: A pulse characteristic meter comprises n integrated converters having nonlinear amplitude response and one integrated converter having linear amplitude response which provide linear and nonlinear conversion of pulses, a processing system composed of a subtraction circuit, band-pass filters, n analog memory circuits, a synchronization unit, a channel switch, an analog-digital converter, a microprocessor computer and a display unit. The input signal is nonlinearly converted and converted pulses are processed by the microprocessor computer to obtain information on basic characteristics: generalized amplitude, duration, area, energy, electric charge, shape coefficients of single and repetitive pulses whose length may be of pico-, nano- or microsecond order.
