Simple square wave synthesis

Adding sinusoidal signals to create a square wave. The square wave is achieved by adding the odd harmonics of the fundamental. The green wave is the synthetized wave. Since it only has 13 harmonics being added, the square wave is not perfect, but the principle is there

I made this because I wanted to use the op-amp mixer circuit

Not bad but illustrating this principle ideally requires no amplifier at all. The ungrounded node shared by each resistor will develop a waveform directly proportional to your output. The op amp serves only as a buffer.

I did something not so different. Check it out. http://everycircuit.com/circuit/6522621793665024
