Help with waveform control: frequency, phase and amplitude
A p.c. based solution is also possible but you would need to write signal processing code in that environment. There are some PC based tools worth looking at in that regard, like audiomulch that might work, but it's been a long time since I used any of that stuff.- sprog

Help with waveform control: frequency, phase and amplitude
I think Sigma Studio could work very well for your intent, the power stage would be all that is required. On real-time audio DSP systems there is frequently an I2S output port - this can be connected to a class-D audio amplifier module, there are a number of manufactureres of pre made...- sprog

Engineering Calculating the size of a capacitor in a sample and hold circuit
your SNR is stated as 60dB, so the factor 10^(60/20) yields 1000 fold power ratio, so your scaled Pjitter is around 0.0003 0.125 - 0.0003 is positive not negative simple math mistake?- sprog

Help with waveform control: frequency, phase and amplitude
Hi, since your system is both generating and also monitoring signals I would suggest that you look in the direction of digital signal processing. There are many processors to choose from but I think that you should look for some 'canned' solutions that are pretty much all in one chip or board...- sprog

What is the potential of dielectric antennas and their applications?
a Google search for 'dielectric antenna' yielded a list of links, one of which was to this forum: https://www.physicsforums.com/threads/dielectric-rod-antenna.950598/ Actually, I've visited before quite a few times, but this time I thought I'd join Hello everyone- sprog
