I'm currently working on a coherent detector for radar. It uses I/Q downconversion and I'm trying to find any possible help on techniques, principles, schematics, common problems with I/Q designs. Any help is appreciated.
Yes, this is a digital oscilloscope application. Can you recommend any parts or things to help me make a better design? I was looking at single-chip instrumentation amps and also building my own from op-amps.
For my current project, I'm reading off many discrete samples of a waveform and then plotting them on a computer. Would it be efficient to simply latch each sample, then immediately transfer it through the USB to the computer? Or should I first store it in chunks of some kind? Can someone...
If i'm trying to measure a relatively slow (~1kHz) AC signal. Can I use an instrumentation amplifier to "read" discrete DC signals so they can be latched and sent to a computer for plotting?
The AC signals can vary and are not necessarily sinusoidal. I had one suggestion of using a...
can you upload your design to a server? i would suggest that if you're trying to make a filter with -80dB/dec, you should consider a passive filter instead of an active. without evaluating your design, i would also suggest confirming that the +/- terminals of the op-amp are wired according to...
