How does a sine wave leads to square wave?
Square waves are equivalent to a sine wave at the same (fundamental) frequency added to an infinite series of odd-multiple sine-wave harmonics at decreasing amplitudes.
Are square waves made of sine waves?
A square wave consists of a fundamental sine wave (of the same frequency as the square wave) and odd harmonics of the fundamental.
What is the difference between sine waves and square waves?
What is the difference between Sine and Square Waves? Sine waves are generated in nature and can be easily reproduced manually. Square waves are not produced naturally, and it requires a set of sine waves to be overlapped. It is possible to make a perfect sine wave, but it is impossible to create a perfect square wave.
What converts sine to square wave?
Sine to square can be converted using a Schmitt trigger circuit. Schmitt trigger circuit is basically a comparator with positive feedback. Figure below shows an inverting Schmitt trigger circuit using OPAMP. Because of the voltage divider circuit, there is a positive feedback voltage.
