ECE 4760: Final Project Report

Introduction For our final project we made a digital vocoder, which could be accomplished over this semester’s remote desktop environment. A vocoder is a synthesizer that generates sounds which are modulated by an input signal. It was originally designed to reduce the bandwidth of voice signals over the telephone, but was never introduced practically. It …

TI RELEASE TPS62912, TPS62913 FAMILY OF LOW-NOISE DC DC SWITCHING REGULATORS

TI RELEASE TPS62912, TPS62913 FAMILY OF LOW-NOISE DC/DC SWITCHING REGULATORS

Texas Instruments released the TPS62912 and TPS62913 family of low-noise DC/DC switching regulators with integrated ferrite-bead compensation. They offer low noise of 20 µVRMS for frequencies ranging from 100 Hz to 100 kHz and ultra-low output-voltage ripple of 10 µVRMS. Traditional low-noise power supply architectures include such technology like DC/DC converters, low-noise LDO, and an off-chip filter, like a ferrite bead. Integrating ferrite-bead …

LED Amusement Park

Overview Our project consists of a 2m DotStar LED strip with 120 individually addressable LEDs and seven accelerometers with the Big Board to depict three different rides that are typically found in an amusement park: the roller coaster, the drop tower, and the bouncer. We implement 1D kinematic equations iteratively to approximate the real-world physics …

NEW RIGOL DSG3000B SERIES 6.5 13.6GHZ RF SIGNAL GENERATORS

NEW RIGOL DSG3000B SERIES 6.5/13.6GHZ RF SIGNAL GENERATORS

The DSG3000B RF Signal Generator series simplifies high power setup since an external amplifier is not needed. Engineers can generate more complex signals without additional hardware using the modulation schemes supplied in the DSG3000B with both internal and external IQ modulation capabilities. Saelig Company, Inc. has introduced the Rigol DSG3000B RF Signal Generator series, improving on the previous DSG3000 …
