Question
Download Solution PDFArrange the following modulation systems in decreasing order of the bandwidth requirements.
A. Single Side Band
B. Double Side Band
C. Vestigial Side Band
D. Frequency Modulation
Choose the correct answer from the options given below
Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFThe least bandwidth is required for Single side band modulation.
The bandwidth of different modulation schemes are as shown:
AM → 2fm
SSB-SC → fm
For angle modulated schemes (FM and PM)
= 2(β + 1) fm
fm = message signal bandwidth
So, for SSB-SC, the bandwidth requirement is minimal.
