Aim
To construct and study the Differentiator circuitApparatus
0.01 $\mu F$ Capacitor,1 K\ohm Resistor, Digital Storage Oscilloscope (DSO), Function Generator, Patch cords, Breadboard, Connecting WiresTheory
Procedure
- Take a breadboard and Connect the circuit see in figure
- Take a function generator and Give Ac 10 V,500 Hz Sinusoidal waveform
- connect the input and output signal of the circuit in Digital Storage Oscilloscope
- Observe the input signal and the output signal
Observation Table
(1) Sinusoidal Wave
(2) Triangular wave
(3)Rectangular wave f=300 Hz
(4) Rectangular wave f= 1KHz
if f = 1KHz, T =10-3
RC = 10-2
*10-3
s = 10-5
s of R= 1K\ohm , C = 0.01m F
Phase angle between input signal and output signal
tanq =(1)/(2p fRC)
so frequency increase q decrease,frequency decrease q increase
tanq =(1)/(2p fRC)
tanq max=¥
q = 90\deg
100 = (T)/(2p RC)
RC =(T)/(100) =10-2
Result
frequency varies from 100 Hz to 900 Hz.So, we can easily say from observation that the Differentiator circuit gives output waveform which is the differentiation of the input signal.
