1. All Application notes can be found on Cypress website
2. There are several ways to measure amplitude of the Sin wave with PSoC.
AN62582 - AM Modulation and Demodulation - is one example.
AN60580 - SIO Tips and Tricks in PSoC® 3 / PSoC 5LP - another option (see Tip 5 - half wave rectifier, and Tip 6 - peak detector).
Using Modulator Input of DelSig ADC, with frequency locked to the input Sin wave.
Entering "appnote finder" into the "Keyword Search" field shows at least this result.
I've got a slow internet connection (2Mbit/s), but it takes (at this time) not very long(2-3s) to get a result.
What characteristic of sine are you trying to measure ?
Peak, RMS, Average, Freq, Period, Phase.....?
Describe your measurement a little more.
The specifications had changed several times, and then so did priorities so the project ended up being shelved for quite some time. It wan't till recently that some life had beeen put back into the thing, so in all honesty there has not been any progrees worth merit.
If you had read my reply to Bob in another thread you would see why I have asked that question again. Good memory by the way :)
As far as the requirement for this I am looking to measure a 1v p/p sine wave ay 50khz. It can be either the p/p value, or RMS value. That's essentially it. I had been using an external RMS to DC converter by Linear Tech, but I would prefer to lower the component count as much as possible.
I will look this over and report back
