LAB 14- Basic Audio Amplifier Date: 12/7/18Abstract:Task of developing basic audio amplifier circuit. Implementation of topics throughout course to successfully obtain results desired. Utilization of voltage dividers, op-amp, RLC filters,and current buffers within circuit. Evaluation of power gain throughout circuit to meet required range. Measurements gathered from oscilloscope testing individual components of circuit to test accuracy. Plotting of frequency response for low pass, band pass, and high pass filters within oscilloscope. Gathering of -3 dB points for low pass, band pass, and high pass filters. Equalization of three filters to obtain clearer audio for outputting from speaker. Plots obtained displaying summing of three frequency bands to become one equalized waveform. Usage of volume control for testing of low and high volume output from speakers. Plots of waveform obtained for demonstration of low and high volumes.Introduction: In this project, we were tasked with developing a circuit that ultimately was able to accurately amplify an audio signal that was given to the created circuit. Certain conditions were laid out that were needed to be met within the circuit created to solve the problem given, such as speaker resistance, filter cutoffs, and power of the speakers. The end goal of the project was to
