    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...

    Bipolar transistor

    Hello everyone, I have a little issue here. I know it's not really hard but it has been a moment since I've worked with circuits like this and transistors, so I can't figure out this circuit... The question is: In DC analysis, calculate the bipolar transistor's voltages Vb, Ve, Vc. Deduce the...
