Hello all,
I require some assistance in creating a phase detector circuit or find an IC (even better option) capable of measuring the phase difference of 3 different waveforms. The three waveforms would be sine, square and triangle. The frequency that they would be operated to would be of the order of MHz. it should ideally read frequencies in the range 1-10MHz but i do not mind decreasing the bandwidth.
I was curious if any experienced person knows an IC similar to the AD8302 but mainly with functionality of phase detection. The other features makes this IC too expensive especially when i just want to use the phase detection functionality of the IC.
I think i found an idea where a wave could be converted into a TTL signal. From this, it could be passed through an XOR gate. The duration that "logic 1 or high" is output and compared to the periodic time, this would determine the phase difference.
The problem with applying this logic to my circuitry is that i do not know how to convert. Can someone point me in a direction?
