    I am new to this and looking to create something to record two separate pwm signals.

    The signals will be between 1 and 2 ms

    The processing of the data can be carried out on a pc afterwards so I was thinking of just writing the length of the pulse to an SD card.

    I assume i need to use a microcontroller to achieve this but can anyone give me an idea on which one to go for and where to start!

    Sorry if this is a little simplistic and thanks for any help.

    There are one or two preliminary questions, and then somebody else (not me!) can have a go at giving you the best answer.
    First, how accurately does the measurement need to be made, please? What kind of signals are they - pulsed DC or pulsed AC signal?
    Also importantly - what voltages are involved please?
    My final question is "what about noise?" Where does the signal come from and is it clean, and where does any noise come from?
