Home networks and other dumb ideas Signal Processing DesignLine Blog 1/31/2009 Post a comment My review of the LiquidHD networking technology was too hash, but revisiting the topic just makes me more skeptical about home video networks in general.
Tutorial: Line echo canceller (LEC) and DC offsets Design How-To 1/30/2009 2 comments This article discusses the role a line echo canceller plays in guaranteeing the voice quality and low-speed modem connection stability in VoIP applications when affected by DC offset. It presents a brief overview of echo cancellation implementation schemes, and examines how performance degrades with DC offset and to investigate and remove DC offset.
Replace your MCU's ADC with a tiny 16-bit ADC that integrates a 10ppm/C reference Design How-To 1/28/2009 Post a comment The LTC2460 ADC makes it easy to replace a microcontroller's embedded ADC with barely any additional board space. It is available in a 3mm x 3mm DFN package (as well as 12-pin MSOP package) and offers very good DC analog performance. Unlike many of the ADCs offered in microcontrollers, its linearity, offset error, and gain error are all tested and guaranteed over the full -40°C to +85°C industrial temperature range.
