Thank you to everyone who has helped so far. I've come across the attached circuit for a white-noise generator (found here: Pocket-Sized White-Noise Generator Quickly Tests Circuit’s Response | Electronic Design )
I would like to build this circuit but first I have a question or two. Is it possible to swap the SMB connection out for electrode wires? Or even just simple wires to test what frequency range the circuit produces? The goal would be to produce from 0 - X Hz and then apply a low pass filter with a cutoff at 30 Hz in order to create the 0 - 30 Hz white noise that I need for my project. Please let me know if that is possible with the attached circuit. The circuit is small which is ideal for me. Thanks in advance!
