EXPERIMENT N0. 1(B) SECOND
ORDER ACTIVE HIGH PASS FILTER
AIM: To obtain the frequency response of an active high
pass filter for the desired cut off frequency
PROCEDURE:
1.
Before wiring the circuit, check all the components.
2.
Design the filter for a gain of 1.586
and make the connections as shown in the circuit diagram.
3.
Set the signal generator amplitude to 2v
peak to peak and observe the input voltage and output voltage on the CRO
4.
By varying the frequency of input from Hz range to KHz range, note the
frequency and the corresponding output voltage across pin 6 of the op amp with
respect to the gnd.
5.
The output voltage (VO) remains constant at lower frequency range.
6.
Tabulate the readings in the tabular column.
7. Plot the graph with ‘f ‘on
X-axis and gain in dB on Y axis.
