Abstract

(This instruction box is to be deleted before submission of the Lab report)

What is an Abstract?

This should include a brief description of all parts of the lab. The abstract should be complete in itself. It should summarize the entire lab; what you did, why you did it, the results, and your conclusion. Think of it as a summary to include all work done. It needs to be succinct yet detailed enough for a person to know what this report deals with in its entirety.

Objectives of Week 5 Lab 1:

· Build and test series resonant band-pass filters.

· Build and test parallel resonant band-stop filters.

· Calculate and measure the center frequency and bandwidth of series resonant band-pass filters

· Calculate and measure the minimum output voltage for parallel resonant band-stop filters.

· Use the Bode analyzer to observe and measure the frequency response of the filters.

Introduction

(This instruction box is to be deleted before submission of the Lab report)

What is an Introduction?

In your own words, explain the reason for performing the experiment and give a concise summary of the theory involved, including any mathematical detail relevant to later discussion in the report. State the objectives of the lab as well as the overall background of the relevant topic.

· This lab will review a series band-pass filter at various winding resistances to evaluate the effects of the inductors winding resistance on the center and critical frequencies, as well as bandwidth. After that we will review the output voltage of a parallel band-stop filter at different load resistances to prove that the purely resistive components after the LC parallel connection will not alter the frequency response but can alter the magnitude of the output voltage at the center frequency.

( Note: Connect the Bode Plotter as shown. Set the parameter as shown in the figure as well. Use Set… to set the resolution to 1000. Run the simulation. Use the cursor to find the maximum gain. This point of maximum gain is your center or resonant frequency (f0=107.4 kHz). Also note the gain at the center frequency (-0.828 dB). To find the bandwidth you will find the upper and lower critical frequencies where the gain is -3dB from the maximum. In this case we will record the frequencies where the gain is -0.828 dB – 3 dB = -3.828 dB.)

5. Measure the upper critical frequency as shown in Figure 3.

What is a Conclusion?

This section should reflect your understanding of the experiment conducted. Important points to include are a brief discussion of your results, and an interpretation of the actual experimental results as they apply to the objectives of the experiment set out in the introduction should be given. Also, discuss any problems encountered and how they were resolved.

Address the following in your conclusions:

· What did you notice about the cutoff frequencies for the low-pass and high-pass filters containing the same circuit elements?

· What voltage level does a gain of -3dB correspond to?

· What did you notice about the phase angle of the low-pass filters? Of the high-pass filters?

· Explain the above results in terms of circuit configurations (lead and lag circuits).

· How did changing the resistance change the cutoff frequency of the RL LPF? Of the RL HPF? Of the RC LPF? Of the RL HPF?

· How did changing the inductance change the cutoff frequency of the RL LPF? Of the RL HPF?

· How did changing the capacitance change the cutoff frequency of the RC LPF? Of the RC HPL?
