A frequency multiplying system and method in which a time varying analog input signal is sampled and stored in a memory matrix at a predetermined rate. The signal thus stored is read out from the memory matrix at a different rate and reconstructed into a time varying analog signal. The storage rates and readout rates are controlled by a command signal generator including a master run-up generator run up at a first run-up rate and reset by the fundamental input frequency, the highest level at the output of the run-up generator being continually stored in a memory circuit. Slave run-up generators which cycle at frequencies corresponding to the storage and reading-out of the sampled information are reset upon coincidence of their levels with the level in the memory connected to the master run-up generator. The command signal generator may be in either digital or analog form employing either counters or integrators as run-up generators. The analog input signal may be processed by either digital or analog means.
