Abstract

PURPOSE:To simplify the circuit constitution and decrease the processing time, by giving an operation to a storage device to which the impulse response having a prescribed delay time is successively written and another storage device to which the input signal that varies with every prescribed delay time is successively written. CONSTITUTION:The storage devices HP and XP consisting of RAMs which are capable of reading and writing are provided, and a data Da of an inpulse response series of each delay time is written into the device HP with a series of circulating memory addresses. At the same time, each data Da of the input signal series which varies with a prescribed delay time is written in turn into the device XP through one of a series of circulating memory addresses and for each delay time. Furthermore the reading address of the device XP is designated and preset to a presetable counter C2 which is preset in the writing order of the device XP. In addition to this counter C2, a multiplier/adder M is provided to fetch and calculate the data which are successively read out of both devices HP and XP with every prescribed delay time. In such way, the circuit constitution is simplified.
