Lab 14 - Bandwidth and Frequency

Bandwidth and Frequency

Objective:

Oversee bandwidth and quality factor given from waveform generator at different frequencies, capacitance, and resistance.

Process:

1. Problem - Construct circuit using multimeter, resistor, capacitor, waveform generator, and record values at different frequencies.

2. Built Circuit

3. Data Collected and Analzyed

Resistance = 1 ohm
Capacitance = 1 micorFarad

Resistance = 100ohm

Capacitance = 100 microFarad

Conclusion:

Resonance frequency is the inverse of the square root of capacitor times inductor. Knowing this values leads to further analysis of circuit and the quality of it. Bandwidth can be determined from the half-power frequencies as well.

Lab 13 - Frequency Response and Filters

Frequency Response and Filters

Objective:

Experience practical use with frequency responses of analog filters

Process:

1. Problem - Construct filters and graph their gain magnitude and phase versus frequency contingent off of data collected

2. Materials - .1 microFarad capacitor
                       R_=1000 ohms
                      Waveform generator
                     
3. Circuit Calculations

Theoretical Value of Gain Expected

4. Circuit Built

Circuit Design

Circuit Demonstrated

5. Data Collected

Low Pass Filter Data Values

High pass Filter Data Values

6. Data Analyzed

Low Pass Filter %Error

Conclusion:

The objective was met through successful data collected from the filters. The gain ratio of output voltage to input voltage was relatively close tho theoretical calculations by only 2% in most frequencies. These values determined the validity of our constructed filter.
