ECE 431 Digital Signal Processing Lecture Notes
cobb.ece.wisc.eduDigital Signal Processing (DSP) is the application of a digital computer to modify an analog or digital signal. Typically, the signal beingprocessedis eithertemporal, spatial, orboth. For example, an audio signal is temporal, while an image is spatial. A movie is both temporal and spatial. The
Low Cost, High Speed Differential Amplifier AD8132

The AD8132 is capable of driving either a Category 3 or Category 5 twisted pair or coaxial cable with minimal line attenuation. The AD8132 has considerable cost and performance
Analog and Digital MEMS Microphone Design Considerations

Analog and digital microphone output signals obviously have different factors to be considered in a design. I will examine the differences and design considerations when
