4-Band Personal Eq Device, Carson Kellerman
Electrical Engineering
The device is a 4-band EQ with 3.5mm audio input and output jacks. The device has 4 adjustable EQ bands. Each of the 4 bands are adjustable via knob potentiometers, and are able to boost or cut their respective center frequencies of 150Hz, 400Hz, 2500Hz, and 10kHz from -15dB to +15dB. The device is battery powered off of 1 9V battery and is able to function for 10 hours before needing to replace the batteries. The device has a Total Harmonic Distortion of less than 1% and a Signal to Noise Ratio greater than 60dB. Overall, this device allows music …
Digital Graphic Equalizer Implemented Using An Fpga, Anthony Giardina
Digital Graphic Equalizer Implemented Using An Fpga, Anthony Giardina
Electrical Engineering
A graphic equalizer is a device that adjusts the tonal quality of an audio signal. When sound is converted from a digital format to analog sound waves, there are amplification and transducing steps in-between the two formats. Common devices to perform these tasks are speakers, amplifiers, DACs, etc. Many of these devices exhibit a non-uniform frequency response over the range of human hearing. Thus, it is possible that certain frequency ranges of the audio signal will be amplified and others will be attenuated. To counteract this, an audio equalizer can be used to boost and attenuate certain frequency ranges within …

Honors Capstones
This senior design (capstone) project is an implementation of an audio graphic equalizer using digital electronic components. The goal of this project is to design and develop a lO-band Digital Graphic Equalizer System. The purpose of this project is to control the frequency characteristics of an electronic audio signal. The operation of the Digital Graphic Equalizer System is controlled by and designed around the Motorola DSP56001 digital signal processor which is a microprocessor that can be used for signal filtering applications. The hardware and the software for this project were designed and developed separately and then combined to form the …
