A comparison of frequency division and time division multiplexing system shows that
- $FDM$ requires a lower bandwidth, but $TDM$ has greater noise immunity.
- $FDM$ has greater noise immunity and requires lower bandwidth than $TDM$.
- $FDM$ requires channel synchronization, while $TDM$ has greater noise immunity.
- $FDM$ requires more multiplex while $TDM$ requires band pass filter.
