Hi, Using the THS12082, how does this work? I have signals being sampled from AINP and AINM. Register is set to auto read from the 2 channels. I have tried plotting my buffer contents and it corresponds with the 2 signals that are coming in. However, I wish

Dear Members I want to measure frequency of power line. I am using 16-bit ADC (sampling frequency is 12.8KHz). My question is how to measure frequency with high accuracy (+/ - 8mHz) in presence of Harmonics ( I think it can be done by Appling FFT) . Can any one through some light on this? Thanks in Advance.

Hi all, Is it possible to declare multiple interrupts in 6713. I have been reading about interrupts from Chassings book and according to their example of int11 this interrupt will occur at every sampling period. I do not wish these interrupts to occur infinitely. How can I do that. Also I wish to have three different types of interrupts for taking in and out data from mic and line. Any sugge...

Hello all, I am using the 6711 DSK to do mp3 decoding. I want to know how to play the PCM samples. Can I use the TLC320AD535 on the board? I see it has a 8kHz sampling frequency, will this be a problem to play music? Will the sound quality be bad? Or

Hello All, I am new to DSP programming and am experiencing some difficulties implementing filters on a fixed point DSP (TMS320C6416). To keep it simple, I started trying to implement a single pole low pass filter with a corner frequency of 500 Hz while sampling at 96kHz. I have obtained the quantized filter coefficients using Matlab's fdatool. I have then written down type 1 direct fo...
