Any Techy Freddies out there that know how to build a Sine-Square Wave converter.

It must work within frequencies of 0.1 Hz to 10 MHz.

Any help at all would be greatly appreciated.


and yes i have tried google, but its not been very helpful.

Thanks in advance

That's a difficult question without knowing what the input signal levels are, and what mark-space ratio you need. However the simplest way to square a sine wave is with a schmitt triggered buffer/inverter. You can buy discrete devices to do the job, or go analogue if you prefer.

Some links:

If you want a bit more control over the problem, you could use a bit from an A-D converter (biasing the input to get the right spacing).

Input signal levels are peak to peak from 0.1v to 10v, and we asssume the input impedance is low.
