Fortunately, the function generator accepts an external clock ... used the NIST WWV broadcast and his ears to find when his frequency standard overlapped that of the source, therefore verifying ...

[Debraj] needed a simple signal generator for a project he was working ... he observed that the PC had good frequency fidelity, though it required an additional DC offset as most cards are built ...

Notice, too, that the frequency of the incoming and outgoing signals are the same. Carrier Wave Generator The Wave Generator creates a high-frequency radio signal. The frequency of this signal is ...
