It’s not a matter of trimming away VDC. His circuit is there to be able to add a VDC to the signal, to be able to shift it up or down as desired. The soundcard won’t give you anything that is ...

Some generators operate on unleaded gasoline. Others use diesel fuel ... Encourage everyone to stay away from these hazards. Turn off circuit breakers before the power goes.

A very simple thyristor signal generator circuit which uses a single thyristor, two resistors, a capacitor and a mini-loudspeaker. Once the circuit is switched ti a current source, current flows ...

and using the phase register as the arbitrary-value input. In a prior research project in the communications field, we created a portable, low-frequency (0 to 1 MHz) signal generator design.

As digital systems migrate towards increased integration with higher speeds for complicated signal processing capabilities, timing design has become critical for robust system performance, while ...

[DTSS_Smudge] correctly intuits that if you are interested in an old Heathkit signal generator ... you still see quite a few units in use. Not all of their gear had tubes, but some of our favorite ...
