ABSTRACT:
First to third memories store a plurality of functions constituting polynomials respectively representing at least one-line luminance, chrominance, and sync signal waveforms included in a television testing signal to be generated and a plurality of parameter values for defining the plurality of functions. First to third expansion sections receive the functions and parameter values of the respective signal waveforms from the first to third memories so as to calculate the magnitude values of the respective signal waveforms for the corresponding time base postions. Fourth to sixth memories receive the outputs from the first to third expansion sections so as to store the magnitude values of the respective signal waveforms at the corresponding time base positions for at least one-line data of the television testing signal to be generated.
