Ten signals, each requiring $4000 \mathrm{~Hz}$, are multiplexed onto a single channel using FDM. What is the minimum bandwidth required for the multiplexed channel? Assume that the guard bands are $400 \mathrm{~Hz}$ wide.

Key Concepts

Frequency Division Multiplexing (FDM)

FDM is a method of transmitting multiple independent signals simultaneously over a single communication channel by assigning each signal its own distinct frequency band. It is a key technique in telecommunications that allows efficient use of available bandwidth by dividing the frequency spectrum into non-overlapping sub-bands, one for each signal.

Bandwidth Allocation

Bandwidth allocation involves calculating and assigning the necessary frequency range for each individual signal within a multiplexed system, including any additional spacing to prevent interference. It is critical for ensuring that each channel operates within its allocated spectrum without encroaching on adjacent channels, thereby preserving the integrity of all transmitted signals.

Guard Bands

Guard bands are small frequency gaps inserted between channels in a frequency-division multiplexed system to prevent interference between adjacent channels. They serve as a buffer area to accommodate potential signal variations and spectral leakage, ensuring that the signals remain distinct and reducing the risk of cross-channel interference.
