hello,
i have a 5 in 1 oscilloscope
http://www.ebay.co.uk/itm/PC-USB-2C...731978?hash=item1a014951ca:g:nWgAAOSwYGFUs8Eh
i am trying to get this clipper circuit working,
http://www.electronics-tutorials.ws/diode/diode-clipping-circuits.html
i can get the waveform but not with the correct (same) value. i cant get the (approx) 0.7 volts. i have tried using the function generator but i am having problems understanding how the bias and amplitude work. there are no instructions with this and there are only two knobs on the device (bias/amplitude).
i have tried to look at what these do but cant find an easy explanation.
i think that dc bias (if thats what this is?) is there for adding to a voltage that is too small to measure(?).....is this correct?
amplitude is simply there to provide a sine wave of so many volts.....?
any help or advice with this would be great.
how could i measure the dc bias on the scope?
also, the clipper circuit i am using, i have a 1kohm resistor and 1n4004 diode.
thanks
simon
