ABSTRACT:
There is provided a signal generating apparatus for generating an output signal corresponding to pattern data supplied thereto. The signal generating apparatus includes a timing generating section that generates a periodic signal, a shift register section including a plurality of flip-flops in a cascade arrangement through which each piece of data of the pattern data is propagated sequentially in response to the periodic signal, a waveform generating section that generates the output signal whose value varies in accordance with a cycle of the periodic signal, based on data values output from the plurality of flip-flops, and an analog circuit that enhances a predetermined frequency component in a waveform of the output signal generated by the waveform generating section.
