タ。[Claims for Utility Model Registration] (1) A shift device consisting of a gate array formed of complementary MOS integrated circuits and a digital-to-analog converter, into which transmission data is input and temporarily stored. A transmission Nyquist filter for digital modulation, comprising a register and a counter whose counting operation completes one round every time one bit of transmission data is stored in the shift register. (2) Utility model registration claim 1, which has a fixed storage section inside the gate array whose addresses are the output values of the shift register and counter.
Transmission Nyquist filter for digital modulation as described in Section 1.
