Complex Input
Hi. i read a lot of article focusing on real input. In physical world, does the input in complex form? If exist, where it comes from and what is the application? Or actually it is just theory only? Thanks ... 16 Nov 2009 22:28

Equivalent time sampling
Hi guys! Does anyone know any algorithm used in digital storage oscilloscope? I know that many DSOs use equivalent time sampling technique but what about the digital hardware (or algorithms) to filter and reconstruct the signal?? If anyone knows some papers (IEEE or other) let me know! Thanks a lot! ... 6 Nov 2009 13:39

Jitter generation compare to dithering
Hi, I have a doubt on jitter generation. Wonder is the method to generate jitter signal is that same as dithering generation method? Understand that both are usign random signal generation with different distribution. For example, triangular, rectangular etc. ... 9 Nov 2009 18:51

Boot Flash for TS201
Hello, I've been using the AT49BV040B flash as the boot device for TS201 dsp on my board. I just learned that the AT49BV040B will be obsolete soon and I was wondering what other are using. The best thing about the AT49BV040B device was the driver code was provided by ADI in the Visual DSP+++ example directory. If I... 4 Nov 2009 16:23

Seeking a simple audio energy detection algorithm
Hi, I receive a stream of linear 16 bit audio and need to identify the possibly "interesting" parts vs. plain silence or noise. Just computing the average energy and comparing to a threshold is not sifficient since there may be a background noise. Is there a lightweight adaptive energy detection algorithm? ... 3 Nov 2009 07:04
