Abstract : A sector-scan period computer comprising a pulse-width discriminator and a pulse-interval filter to allow only pulses falling into a predetermined width range and with a given time interval between them to pass is discussed. These pulses are fed to an integrator which provides an integrated signal for each group (burst) of pulses, the bursts being periodic. The integrated signals are divided by two and a pulse is produced for each signal that remains. Extraneous non-periodic signals are filtered out by a period filter and the time between successive pulses is counted by a BCD counter. The counter output is stored in a memory and displayed by a decimal number display.
