Part A-Active Filters

 

 

Week six addresses the concept of active filters and oscillators.  The low, high, bandpass and notch active filters, their circuits, and operating parameters are covered.  The Wein-bridge RC oscillator, its configuration, operation and circuit is discussed. 

TCO #6:

Given an application requiring active filters calculate, simulate and measure filter characteristic of a low-pass, high-pass, band-pass, and notch filter.

A.   Identify the gain-versus-frequency response of basic filters.

a.    Draw the frequency response of a low-pass, high-pass, bandpass, and a notch filter.  Label each axis, the critical frequency, bandwidth and the 3-dB point.

Low                                                   High

Description: Axis

Band                                                 Notch

b.    What is the “order” of a filter?  How is an order created?

B.   Simulate the frequency response of an active low-pass filter such as a Butterworth filter.

a.    Given the following circuit, calculate the critical frequency and the closed-loop gain.

= _________   = _________

Description: Lowpass1

b.    Download “ECT246_Week_6_Low1.ms” from Doc Sharing, week 6.  Run the simulation.  Use the Bode Plotter to find the -3-dB point and determine the critical frequency.

= _________ @ -3 dB

c.    Compare the calculated value to the simulated results.

C.   Prototype the active single-pole low-pass filter and measure and sketch its frequency response, compare and contrast the simulated and measured results. 

a.    Prototype the active single-pole low-pass filter in the diagram above using a LM741 op-amp.

b.    Connect a frequency generator to the input of the filter.  Set the frequency generator’s output to a sine wave at 100 mV peak and as close to 0 Hz as possible.

c.    Connect channel 1 of an oscilloscope to the input and channel 2 to the output of the filter.

d.   Vary the input frequency according to the chart below and record the input and output voltage in the table.  Calculate the other values.

Frequency (Hz) Input Voltage (peak) Output Voltage (peak) Gain Gain dB

e.    Using the Graph Paper.doc file located in Doc Sharing, week 6, plot the frequency response of the circuit.

f.     Locate  for the filter.  Compare its value to the calculated and simulate results.

D.   Simulate the frequency response of an active single-pole high-pass filter such as a Butterworth filter.

a.    Given the following circuit, calculate the critical frequency and the closed-loop gain.

= _________   = _________

Description: High1

b.    Download “ECT246_Week_6_High1.ms” from Doc Sharing, week 6.  Run the simulation.  Use the Bode Plotter to find the -3-dB point and determine the critical frequency.

= _________ @ -3 dB

c.    Compare the calculated value to the simulated results.
