| Zusammenfassung: | A complex signal generator uses the combination of data signals held in several different read-write memories. Address stages are used to access the contents of a number of read write digital memory stages. The address cycle is controlled by a separate cycle control unit that is directed by a programme held in a memory. The outputs of the memories holding signal values are converted to analogue form and are added together to generate the complex analogue signal waveform. A range of complex signal waveforms may be generated and the time base varied by loading the memories with different parameters. |
