Abstract
A waveform display signal generating apparatus is provided in which a result of calculation processing of digital data in a CPU is visualized and is converted into a television video signal for display on a screen of a television receiver under production. The apparatus verifies digital data processing on a screen of a television receiver under production and provides a simplified verification system. A signal digitized at an A/D converter is digitally signal processed at a data processing circuit. The data under digital signal processing is supplied to a CPU through a CPU interface circuit, is calculated for converting into a graph and then the converted data is stored in a RAM in a form of a bit map data. The bit map data is converted into an analog signal at a D/A converter, is further converted into a television video signal at a television encoder and then is supplied from a video signal output terminal to a video circuit of a television receiver under production. Thus, a graph calculated at the CPU is displayed on the screen of the television receiver.
