EBAO-3 Audio Oscillator Kit
EBAO-3 EDUCATIONAL BLOCK AUDIO OSCILLATOR
Sine waves are "pure" audio tones typically used to test audio equipment. This audio oscillator kit produces sine wave audio signals. Output amplitude and Frequency is adjustable.
Use this kit to learn the "signal injection" method of audio-circuit troubleshooting, or connect two or three together to produce complex audio signals such as DTMF (Dual-Tone Multi-Frequency) "phone tones." Connect to the audio amplifier (EBAA-1) and hear the sine wave tones.
Power requirement +9 VDC,
PC Board size 2.25" x 2.75"
