*** Two Many Tone Generator ***
This project started out to be a simple low distortion two-tone generator but...
it developed a severe case of feature creep so, now, it generates:
1. Single Tones from 100-6400 Hz in 100 Hz steps
plus a quadrature output for Silly Side Band experiments
2. Two Tones with a 300, 400 or 500 Hz low frequency and
a 1700-3200 Hz high frequency in 100 Hz steps
The Sync output (lower trace) is derived from the lowest output frequency.
3. Fifteen Triple Tones combining two each of 300, 400 & 500 Hz
with a 5 different high frequencies
4. White Noise, shown in pulse mode
The Sync output follows the pulse gate in pulse mode
All of these signals may be either continuous or pulsed with a 50% duty cycle
at the rate of 10, 20 or 50 cycles of the lowest frequency being generated.
Finally, the generator has crystal accuracy and -90dB distortion.
