Waveform shaping apparatus.

摘要

A waveform shaping apparatus (11) includes a shift register (1) having a clock input terminal (6), data input terminals (5) supplied with respective bits of a digital input signal and a plurality of data output terminals, and a plurality of coefficient multipliers (21,22,23,24) connected to the respective data output terminal. A 2's-complement binary code offset within a predetermined range is used for representing the coefficient of each of the multipliers and such coefficient is controlled by manipulation of ON/OFF switches.
