Howdy, I'm using the audio daughter card on the 6713 DSK, which is sampling stereo 48 kHz. I believe this rate is fixed, via the jumpers on the board. I want to sample the data, but then decimate it to a lower rate, and send it back out to the daughter card. Howe

Hi everybody, I have a simple question. I am using the DSK6711 which has an AD535 on board. The AD535 has the sampling frequency limited to 8 Khz. Does this also mean that i will be unable to play out audio through the ad535 at a higher frequency, or is it just that the input analog signal will be sampled only at 8 Khz? Thanks and regards -Sunil

Hi, I am trying to implement the MPEG-2 layer-3 multichannel decoder on C6x, backward compatible with MPEG-1 layer-3. I am new to this work and I don't have any source code to implement this decoder, but I got spec 13818-3. Actually I am trying to build this multichannel decoder around the MPEG- 1 layer-3 and its low sampling frequency (lsf) stere

1. How do we change the DAC settings on the DM642 board ? The method we tried out to change the Sampling rate from 48 KHz to 8 KHz on the TLV320AIC23 chip is as follows: a. We changed the following line in the file "..\ti\ddk\include\aic23.h" from #define AIC23_REG8_DEFAULT AIC23_REG8_48KHZ to #define AIC2

Hi I am currently working on a project in which the input signal is an eeg signal.the processor that i use is TMS320C6713DSK.(the signal has been stored in an excel sheet format) the eeg data has a bit rate of 256samples/sec,but the processor sampling rate is 4KHz.hence i am unable to pass the data into it. I heard that the i/p data need to be oversampled,but i don't know how to do i...

Hi friends, I am doing speech compression using DCT and getting speech back using IDCT. I am using simulink to do this.  As my proj is LPC in tht i am sending residual signal after compressing using DCT. My problem is, Whn i insert the DCT      (Radix-2 algorithm which requiers number of inputs as powers of 2) and IDCT

I have seen many examples of connecting an ADC to the McBSP port where the sampling rate is controlled by a clock generated by the DSP chip. I have an application where the clock will come from an encoder connected to the shaft of a motor. I am trying to figure out if there is an efficient way to do this with the DSP architecture. I don't think it can be done using the McBSP. The s...

I have a few questions about C6713 DSK. Is it possible to integrate a daughtercard including ADC working around 300 ksps to C6713. If yes, would you like to suggest this type of products? I am using Matlab/Simulink to obtain CCS projects. Is there any products having simulink adc/dac blocks. I want to design FM demodulator+BPSK demodulator. My IF frequency is 70 Mhz, video bandwith 138kHz...

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.

I am working on a project that the audio signal is interpolated from 8kHz sampling rate to 48kHz. I am using C6713 DSK broad. I configure the AIC32 codec with ADC of 8kHz and DAC of 48kHz. At the same time, I use ping-pong buffer to save incoming and outgoing data. Interpolation is achieved. However, I get the noise output. When I configure AIC32 codec with ADC of 8kHz and DAC of 8...
