Hello,
I am working with a plate antenna to measure variations in an electric field in the 0 to 100khz range. My teams advisor does not believe we will be able to distinguish frequencies that are in this range using the plate antenna. The setup is the plate connects to an op amp that has a feedback path with a capacitor in parallel with a resistor. It acts as a high pass filter, so the frequency range will actually be about 1-100kHz.
The plan was to take this signal digitize it, and plot the FFT of the signal. Our advisor does not think it will work. Does anyone know anything that would help? We need to be able to distinguish different frequencies within the 1-100kHz bandwidth.
We thought it would be able to work as we have been able to generate signals that were composed of multiple sinusoids and even sinusoids and square waves(generated using matlab). Using these signals we were able to find the frequencies in the original signal. We thought this would apply to the data from the time varying magnitude of the E-Field.
Thanks for any help or advice!
