WebNov 22, 2011 · 4. In terms of an I/Q constellation diagram (i.e. a phasor or real/imaginary diagram), any frequency deviation from the center frequency would result in the IQ vector rotating around in a circle, with the speed of … WebAug 24, 2013 · FSK Interface. One of the projects on my relatively long-term list has been an FSK interface. The reason it hasn’t been urgent is that the Elecraft K3 has superb AFSK circuitry that carefully controls the bandwidth of the transmitted signal. So there was no urgency to move to FSK. However, with the recent K3 firmware upgrade that also added ...

WebNov 5, 2009 · ASK, OOK, FSK, QPSK modulators and demodulators. WebFor an FSK modulation with coherent detection, in order to ensure orthogonality, the frequency separation between symbols is $ \Delta f=f_2 - f_1 =1/2T$. However, in case of non-coherent demodulation, which must be this value $1/2T$ or $1/T$?
WebDemodulating an FSK signal in Python. I am trying to write a Python script that can demodulate an FSK modulated audio file and return the data encoded in the audio. The data being transmitted is GPS NMEA strings which are embedded as the audio channel in video files. Basically, text is encoded with FSK modulation, and I am trying to retrieve ... WebFeb 22, 2024 · Two: Find the peak signal power of one of the tones. Estimate the median of the noise floor power. Divide peak signal by median of noise floor: SNR = peak / median. This also seems weird because depending on the snapshot of data, the amplitude of the tones is different. SNR isn't changing but this method doesn't give a constant SNR.
