Hi i am working on a dissertation project known as the lock in amplification of a signal buried in noise .... i am buildin da basic ciircuit but wht i am confused about is how do i add a noise source in a breadboard using basic electrnic components ... i will really appreciate da help
hi .... do i jus connect da zener diode in reverse biased series mode .... n provide a voltage more than da breakdown voltage .... if dats da case i am tryin it in multisim electronic workbench but i am not seeing any noise in da output .... may be i have da circuit wrong .... any help ?

sorry about earlier for using short texts , anyways i am not entirely sure about how to connect the circuit either, i am pretty sure whatever i have done is stupid, I just tried to follow what one of my seniors wanted me to do, i have attached a picture file and i hope you people can help me out, thanks a lot so far

I am confused about how to check the signal for noise in it in multisim, i mean since i am using a dc power supply the only thing that i notice in the oscilloscope is a straight line without any noise interference in it, what am i missing out? your help will be greatly appreciated
