A staple of the radio amateur’s arsenal of test equipment in previous decades was the dip meter. This was a variable frequency oscillator whose coil would be placed near the circuit to be tested, and ...

The circuit was designed to create a frequency convert with the use of a crystal oscillator for the conversion of 10 MHz to 1 MHz. 7404 – a hex inverter utilizing TTL to achieve high speed at nominal ...

Of all the low-frequency oscillator configurations, the Wien Bridge has to be the friendliest and easiest to get along with. Like a faithful dog, it behaves itself regardless of the weather, is not ...

The circuit was created to produce an oscillator operating at low frequency for use in the production of electronic music and experimenting and testing tone controls. Oscillator – an electronic ...
