    Adding DC Offset bias to AC Signal

    I am currently completing a project and it includes using a Step-Down Transformer to bring the mains Voltage (230V RMS 50Hz) down to 6V RMS. From here I have used a voltage divider to step down to 3.3Vpk-pk. However, the ADC for the microcontroller I am using has a range of 0-3.3V, and my signal...

    Paired Op Amp Input Offset Correction

    Each of the op amps shown in the attached circuit diagram is powered from differing rails (+, gnd and gnd, -) to produce two identical, but DC shifted, outputs. In addition, the input signal is referenced to the negative rail instead of ground. There is a reason for this relating to balanced...
