SUMMARY
The discussion focuses on calculating frequency deviation in frequency modulation (FM) using Carson's Rule. The input analog signal is 1.2 kHz, with a minimum bandwidth requirement of 3.6 kHz to avoid over-sampling. The signal is transmitted over a distance of 1.1 km with a bandwidth of 12 kHz on an FM carrier, specifically in the GSM reverse band at 875 MHz. The formula used is Bandwidth requirement (CBR) = 2(Δf + fm), where CBR is 12 kHz and fm is the message signal bandwidth.
