Can anyone help me in my mini project? :(
The question is..

" Design a period counter: a device to measure the number of microseconds in one period of an input waveform. Use a Schmitt comparator to generate TTL. Use a 1.0Mhz clock frequency. Make it works so that pushing a button initiates the next measurement. "

It's requires a components list and a circuit diagram/block diagram. Anyone have any idea or infomation please tell me. Thanks!:)
