Frequency Central System X Oscillator PWM


Published on May 14, 2016 cane creek

"This is the Frequency Central System X Oscillator I built its made following the same schematics as the classic late1970’s Roland 100M VCO just instead of a pair of ua726’s it uses CA3046 instead, I didn’t realise the manual knob let you adjust the pulse width you learn something new everyday with an oscilloscope at hand. Anyway the Pulse width modulation appears to be working fine and the Square Wave is pretty much Square lol."
