What is VSB?
SSBSC modulated signal has only one sideband frequency. Theoretically, we can get one sideband frequency component completely by using an ideal band pass filter. However, practically we may not get the entire sideband frequency component. Due to this, some information gets lost.
To avoid this loss, a technique is chosen, which is a compromise between DSBSC and SSBSC. This technique is known as Vestigial Side Band Suppressed Carrier (VSBSC) technique. The word “vestige” means “a part” from which, the name is derived.
VSBSC Modulation is the process, where a part of the signal called as vestige is modulated along with one sideband.
How to Calculate Bandwidth of VSB?
Bandwidth of VSB calculator uses Bandwidth of VSB = Maximum Frequency DSB-SC+Vestige Frequency to calculate the Bandwidth of VSB, Bandwidth of VSB is the sum of the bandwidth of SSBSC modulated wave and vestige frequency. Thus VSBSC modulated wave contains the frequency components of one side band along with the vestige of other sideband. Bandwidth of VSB is denoted by BW_{VSB} symbol.
How to calculate Bandwidth of VSB using this online calculator? To use this online calculator for Bandwidth of VSB, enter Maximum Frequency DSB-SC (f_{m-DSB}) & Vestige Frequency (f_{v-DSB}) and hit the calculate button. Here is how the Bandwidth of VSB calculation can be explained with given input values -> 250 = 150+100.
