Hi everyone,
I have made a triangle wave from a 555/4013 square wave circuit using a integrator and then into a sine wave. But on low frequencies the triangle wave is high in amplitude (very loud) but on high frequencies it becomes low in amplitude (very quiet), I need to fix this problem,
I was thinking if I could take a audio source from the square wave oscillator, turn it into a voltage output and put it with the amplifier pot that makes the triangle louder as it sweeps from low to high. This could work. Any ideas how to turn a square wave audio source into a smooth voltage that climbs to make the triangle amplitude equal as it climbs up in frequency?
Or has anyone got any better solutions? I would prefer to use analogue circuits.
This is where I got the square to triangle integrator circuit from:
