    Graduate Understanding Function Generator Noise for Calibrating Noise Measurements

    Thanks so much. I am strongly tending towards measuring the noise power in high value resistors ATM. While at it, might I ask (might look stupid). The spectrum analyzer I use give a whole range of the spectrum different PSDs. In fact I see something similar to the 1/f in the result. I am...

    Graduate Understanding Function Generator Noise for Calibrating Noise Measurements

    I want to calibrate my measurement setup for noise measurements. I have taken some measurements but I need to confirm that my measurement correlates with the Johnson noise theory. To do this, I have tried measuring resistors but I seem not to get the right results. My supervisor then...

    Graduate What is the role of silicon oxide in graphene visibility experiments?

    Hello all Quickly, does anyone have an explanation if any for usage of silicon oxide in graphene visibility experiment?? I have a seminar presentation in one hour and I know its a possible question from one of the supervisors. Thank you
