hi,

   i need some sample project using dac and adc in same project like signal loopback, signal filter (low pass)....

need more projects on psoc3 ?., where could i get ?., i want to play with psoc3 ..........

 

Many Thanks,

Thiyagarajan.S

If you place an A/D, DAC, Filter, UART on a schematic,. right click it, select "find example project",

and you will be able to select an example to add to your project, or open in a new project window.

A lesser known tip : Even the ADC has an LPF!

Not sure why you are posting on a 4 month old thread.

 

There are 4 components in the DelSig that exhibit LPF responses, comb in

fact on one, the input buffer, the decimator, ther input switch cap stage, and

the post processor.

 

That being said the input buffer only minimally programmable as a LPF, its

response simply a result of GBW changes due to operating bias power. The

Decimator and post processor also not really independently programmable

as a LPF, their response set by sample rate clock. Stated another way, once

sample rate is set, the response behaviour follows, not independently pro-

grammable. More importanly the comb behaviour can be used as a notch for

something like power line rejection. Lastly the sw cap input stage again not

independently programmable.

 

Regards, Dana.

@Bob: you know that Smileys are originally text-based ;-)

Anything else is line noise (though I think that some of https://en.wikipedia.org/wiki/List_of_emoticons would pass that test as well :)
