Hi.I have a project,i haven't an idea yet,firstly i want to receive your ideas and then design my circuit.If you have an idea about this,please share with me so i can evaluate these and make my circuit more accurate.Project is as following.
WAVEFORM TYPE DETECTOR
The circuit will detect the given input waveform.The input waveform will be a triangular,sine or square wave,with a frequency of having 1000-3000 Hz and having an AC amplitude of 2V to 4V and a DC offset of -5 to 5 volts.In this circuit project,using an multimeter,voltmeter,oscilloscopes or any instrument which measures voltage or current is not allowed.But,red and green LEDs can be used as indicators.
