Audio
test oscillator audio test oscillator circuit, This generally results in a
square wave if the frequency of oscillation is low enough relative to the
amplifier's bandwidth |
|
Crystal Controlled
Oscillator schematic of a low frequency sine wave oscillator featuring low
distortion, wideband operation and crystal control.The circuit, originally
developed for laboratory use, employs low cost AF bipolar transistors for the
oscillator and amplifier sections and a JFET for loop-gain control. Operation of
the oscillator in the 10 kHz to 500 kHz frequency range has been found to be
excellent, while measured distortion is kept under 0.1 percent |
