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
