Signal processing and conditioning with diodes

Introduction In many circuits employing diodes, the constant voltage drop model is sufficient to describe the diode behaviour. Figure 1 illustrates the constant voltage drop model VF Forward Voltage drop OR Diodc ON Diod rr Figure 1 In a clipping circuit, the output voltage will be proportional to the input voltage as long as the input lies between specified reference levels. Outside this range, the output is clipped, it remains essentially constant, and is no longer dependent on the input. Clipping circuits find important uses in wave-shaping and signal processing applications Required Equipment Prototyping board Digital Multimeter (DMM) Signal Generator oscilloscope (CRO) IN4004 diodes (X2) 10 resistor 100k2 resistor 100nF capacitor 47nF capacitor

Explanation / Answer

as you see the equation

diode will pass current only if input is above 3 v during +ve half and less than -4 V during -ve half.

but here v(in) is not given

so, for different value of V(in) different V(out) will be there. so, without knowing V(in) value you cannot predict V(out).still I am giving some conditions as example

If V(in)< 3v current never pases so V(out)= V(in). so graph is a straight line through origin with slope 1.

plz rate it and if any other doubt ask
