Hi Jim and all, I suspect that the aliasing problem may not be in the sound card, but rather in the driver's software sample rate conversion. Most recent Windows systems are set up to always run the
Dear LF Group, Aliasing certainly is significant in (fairly recent) sound cards - I designed my Jason TX implementation to take audio from the sound card at 5kHz, and mix/filter it up to 137kHz. When
Hello Group, If someone knows an easy way to get started in USB programming, I'd like to try interfacing one of those PIC's with fast ADC and USB interface to a PC. (For a dummy like me, who does not
Yes please, I would like the PIC code. I did something similar in the past using a 16C71 PIC with 8 bit A/D. This sampled at 4kHz and formed I/Q samples at 1kHz output rate as follows for every 4 inp
If anyone does design a USB interface for a medium to high speed A/D they could do well marketing it commercially. And then go on to look at other USB driven test equipment modules. As far as I can s
Anyone willing to design an USB interface for Intersil HSP50016 DDC? Together with an AD9260 ADC it would make a nice little front end for an LF SDR. Better chips are probably available today but the
Hi Alan, I'm afraid that the sigma-delta convertors which almost completely dominate the audio world nowadays don't have that aliasing 'feature', thankfully. Simplistically, they're a single-bit conv
Hi all, An S&H with 1 us sample time and 100 us hold time is very easy for today's parts. The state of the art is several orders of magnitude better for both parameters. Take a look at this A/D with
Hi Alberto, we are all jumping on you for your over-enthusiasm........but it occurs to me that this is a 24bit card....than may be more significant. It has the potential to give the level of s/n we
