nco sample rate converter clock
Let me try to explain the problem once again and hopefully it'll be clear this time. There is an analog signal with embedded sync pulses. The A/D converter takes the analog signal and outputs digital data at 100MHz fixed rate. The sync pulses are 1us apart, so...
fractional polyphase decimator
Most answers above are addressing sample rate conversion, which is somehow different from my original question, but the two are closely related.
For sample rate conversion, one can use NCO or PLL to generate another clock and simply use it to re-sample the input...
sony service menu init tv
I've repaird such a TV and can share with you my tips. The symptom was no power. I checked the power supply and found Q601 and Q602 (2SC4834) shorted and fuse resistor R607 (0.1 ohm, 1/2W) blown. Apparently the power supply was shorted -- this is usually caused by...
decimation filter
How do I implement a fractional interpolation/decimation filter in hardware? I know how to do an integer interpolation/decimation filter (by using polyphase filters), but don't know how to do a fractional one without overspeed. For example, to convert 100MHz sampled data to...
As far as I understand, all the different flavors of linux use the same kernel, so it shouldn't be a big deal. Having said that, big EDA vendors (Synopsys, Cadence, etc.) still use redhat 7.3 as the reference linux OS for their product release.
I have never used debian or suse, but I heard that...
matlab ntsc decode
Thanks for the info. Both encoders were indeed revoked from opencores.org.
I know a free IP is difficult to find, but does anyone have a demo code in C or Matlab such that I can at least get the filter paramters? I have written a Matlab decoder using filtfilt() function...
pal decoder c code
Does anyone have any kind of video decoder source code in Verilog/VHDL? www.opencores.org has a video encoder, but there is no decoder. I just want to experiment different comb filtering techniques.
If no decoder source is available, I'd appreciate if anyone can provide me...
