DIGITAL MULTIFREQUENCY SIGNAL GENERATOR |
摘要 |
<p>Tone signals are generated at selected frequencies by employing a programmable digital divider in conjunction with a low-pass filter. Transient signal components are minimized by selectively shaping and biasing the divider output. Pre-emphasis of the divider output amplitude at the frequencies of interest allows use of simplified filter arrangement.</p> |
