摘要
The digital filter comprises a memory (31) storing filter coefficients, a multiplier (30) multiplying internal data of the filter by the said filter coefficients, an adder/subtracter (33) adding the results of the multiplications to other data obtained in the filter, a delay circuit (34) connected up to the output of the adder/subtracter, a shift register (35) storing and retrieving at the requisite the time the data coming from the delay circuit, and an interlock output memory (36) storing a datum output by the filter. These various elements are interconnected with the aid of switches (37, 38) in order to perform the successive operations of multiplication and addition during a cycle. This filter, equivalent to a lattice filter, can be used in a voice synthesizer. IMAGE
