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 …

Design, Implementation, And Analysis Of A Time Of Arrival Measurement System For Rotating Machinery, Bryan Will Hayes
Masters Theses
The Non-contact Stress Measurement System (NSMS) acquires critical time of arrival data from multiple optical probes viewing a rotating piece of machinery, such as blades on a turbine engine rotor. The signal from each probe must be converted from light energy to an electrical signal, conditioned, and timed by a high speed counter to measure the time of arrival of the rotating machinery. This thesis describes, in detail, the design and analysis of the photo-detector electronics, analog signal conditioning electronics, and the timing electronics utilized in measuring the time of arrival. To measure the time of arrival with precision, the …
