Square wave ring modulationAttibution: DivKid
XOR logic will combine two square waves in a way that emphasizes their differences
If you feed the square waves from two oscillators through a binary XOR logic cicuit, you receive a “CMOS-style ring modulated” pulse wave at the output.
- patch two square waves to the inputs on an XOR logic circuit
- patch the output into a low pass gate or filter/VCA combo
