The constant on-time (COT) control method used by the LM3402 and LM3404 constant-current buckregulators provides a balance between control over switching frequency and fast transient response.Normally this quasi-hysteretic control senses the input voltage and adjusts the on-time tON of the powerMOSFET as needed to keep fSW constant. Investigating a little more deeply reveals that tON is in

This document summarizes the results of a performance analysis on the LMS-filter based line echo canceller (LEC) implementation using TMS320C6201 digital signal processor. The CPU throughput internal data memory and power dissipation requirements for processing are discussed.

The filters described here are user programmable double biquad filters for tone detection. The filters are implemented on the Texas Instruments (TI)(tm) TMS320C2xx digital signal processor (DSP). The filter program includes an energy estimation stage. Examples of applications are CPTD (call progress tone detection) fax tone detection answer tone detection etc. for telephony or modem.

Circuit Applications of Multiplying CMOS D to A Converters

Multiplexers have been used for acquisition of quasi-static signals for a long time. While these signals usually have a low bandwidth of only a few hertz, applications generally require that the multi

AN-656 Understanding the Operation of a CRT Monitor

This report covers both the theory and implementation of a single chip TMS32020 digital voice echo canceller. The single-chip system can perform a 128-tap for 16-ms echo cancellation for telephone network applications. The echo canceller is implemented in accordance with the CCITT recommendation (G.165). A simulation has been performed to test the echo canceller and the result exceeds the CCIT

This application note describes how to simultaneously filter 4 or 8 sampled signals in a single GC2011 Digital filter chip. The input data is multiplexed in a time division multiplexed (TDM) format. In the dual path mode the chip will process two TDM data streams each containing four signals for a total of 8 signals. In the cascadedmode the chip will process a single TDM stream containing four
