Why radio exhibits better sensitivity with a wider deviation when Rx bandwidth remains constant
I used an RF generator transmitting FSK packets with a datarate of 50 kbps. The deviation was 12.5 kHz. With this combination of datarate and deviation the modulation index is 0.5. I found that my ...

Maximum achievable SNR (SNR before LNA)
I am trying to understand the concept of noise figure and the best achievable SNR.
The noise figure is a measure how much a device degrades the SNR. Say I have a receiver with a NF of 16dB, then the ...
