Nov 25, 2023 · Basically what I think I have learned from all of the videos I watched on the topic is that the I signal is the captured signal multiplied by some sine wave, while the Q signal is also …

Dec 28, 2013 · I used a signal analyzer to get IQ sample data from a blue tooth device. The IQ data received is in the form of a .MAT file and I examined the file contents and see an + ibn …

Oct 26, 2020 · Yes and no. I/Q data is the result of demodulating an RF signal (i.e. a signal riding on a carrier) with a pair of local oscillator signals that are 90 degrees out of phase. I think …

Aug 2, 2016 · As a newbie I am trying to understand I and Q modulation and demodulation. So from what I read the I and Q components of a signal separately mix with RF signals that are 90 …

Mar 18, 2020 · I am trying to understand the basics of IQ modulation. The amplitude of a demodulated IQ signal is given as $\\sqrt{I^2 + Q^2}$ which is easy to understand from the …

The SDR (or any general digital signal processing system) receiver takes the received RF signal, and down-converts it from the carrier frequency to the baseband, converting a real bandpass …

Jan 10, 2025 · I think reason we have I/Q samples in SDR is to avoid losing information of the portion of signal falling in the negative part of frequency spectrum. As a result, this make …

The signal S S is represented as a series of I/Q pairs at a sample rate Fsr = 10MHz F s r = 10 MHz. I am told that the center frequency of the recording is Fcenter = 7MHz F c e n t e r = 7 MHz.

Thanks @DanBoschen. Given how sparse the datasheet is, I don't have high hopes the manufacturer will provide assistance. It basically says only that the IQ data is 120-360 µVrms. …

Dec 14, 2014 · I am getting I/Q data from a software-defined radio. I want to do some stuff on signals in the data, but only if it exceeds a certain range. What is the general procedure to get …
