# Frequency Response of Netwroks (Electronic Engineering) - Lab Report Example

## Extract of sample Frequency Response of Netwroks (Electronic Engineering)

Current was determined by monitoring the voltage across 100 ? resistor. The CRO was used to record the current and voltage waveforms. The above procedure was repeated for the series connection of a resistor and inductor. Voltage across the inductor was measured at 100 Hz. The frequency response of the RC low-pass filter was measured over the frequency range 100 Hz to 100 kHz. At R = 1 k?, C = 0.01 µF, the attenuation at 15 to 20 frequencies were logarithmically recorded over this range. This procedure was repeated with R= 10 k?. The LF oscillator was connected to the RLC series circuit and with R=100 ? the voltage across the capacitor and inductor, and current through the circuit at frequencies between 1 kHz and 100 kHz determined by measuring the voltage across the series resistor. The band-pass filter circuit was constructed and voltages Vo and Vi measured over the range of frequencies 1kHz to 100 kHz. The band-stop filter circuit was also constructed and Vo and Vi again measured over the range of frequencies 1kHz to 100kHz. A Twin-T filter was then constructed with R1 = R2 = 100 ? and C1=C2=0.01µF. ...

The small difference between the calculated value and the measured value may be due to inaccurate readings or as a result of rounded figures. 2) Measuring VL and VR in figure6 with R=100 ? and C=0.01uf Table.2 ?

## Summary

Frequency Response Networks Tutor The main objective of this experiment was to investigate how capacitive and inductive reactance’s vary with frequency, plot the frequency response of a simple RC filter, plot the variation of current with frequency in a series RLC circuit and determine the resonant frequency and Q factor and to evaluate simple band- pass and band-stop filters…
