Circuit Analysis
Hi
I have been given a circuit to connect my microcontroller without any explaination or how the circuit was devised like this way.
So I would be very grateful if you help me to analysis the circuit.
The PWM (2.5v) is generated to waveform at 50Hz but it is square waveform. I understand that two RC filters are included in this circuit to implement 500Hz low pass filter. The question is why two low pass filter is needed?
The output of circuit must be approximately 200mV and I understand that attenuation approach is used but I have not got a clue how to work it out.
How to calculate the voltage between two 33kohm
I look forward to hear from you asap
