Greetings,
I need to convert a varying frequency square wave signal to the corresponding sine wave frequency.
Firstly, the square wave is not symmetrical in that the Off time is about 7 times the On time.
The voltage of the square wave is relatively constant 13.6 volts ( I am using a battery charger as a power supply). The frequency range is from 0 to 150 Hertz, quite low.
The sine wave does not have to be perfect.
I dont know where to start
