What is DSB-SC?

In the process of Amplitude Modulation, the modulated wave consists of the carrier wave and two sidebands. The modulated wave has the information only in the sidebands. Sideband is nothing but a band of frequencies, containing power, which are the lower and higher frequencies of the carrier frequency.
The transmission of a signal, which contains a carrier along with two sidebands can be termed as Double Sideband Full Carrier system or simply DSBFC.
However, such a transmission is inefficient. Because, two-thirds of the power is being wasted in the carrier, which carries no information.
If this carrier is suppressed and the saved power is distributed to the two sidebands, then such a process is called as Double Sideband Suppressed Carrier system or simply DSBSC.

How is bandwidth of DSB-SC obtained?

The bandwidth of a signal is always of significance for many reasons, but predominately, it determines how many channels (or stations) are available in a specific band. Thus, the bandwidth of DSBSC wave is same as that of AM wave and it is equal to twice the frequency of the modulating signal.

How to Calculate Bandwidth in DSB-SC?

Bandwidth in DSB-SC calculator uses Bandwidth in DSB-SC = 2*Maximum Frequency DSB-SC to calculate the Bandwidth in DSB-SC, Bandwidth in DSB-SC is equal to twice the frequency of the modulating signal. DSB-SC is an amplitude modulated wave transmission scheme in which only sidebands are transmitted and the carrier is not transmitted as it gets suppressed and is an acronym for Double Sideband Suppressed Carrier. Bandwidth in DSB-SC is denoted by BW_DSB symbol.

How to calculate Bandwidth in DSB-SC using this online calculator? To use this online calculator for Bandwidth in DSB-SC, enter Maximum Frequency DSB-SC (f_m-DSB) and hit the calculate button. Here is how the Bandwidth in DSB-SC calculation can be explained with given input values -> 300 = 2*150.

FAQ

What is Bandwidth in DSB-SC?

Bandwidth in DSB-SC is equal to twice the frequency of the modulating signal. DSB-SC is an amplitude modulated wave transmission scheme in which only sidebands are transmitted and the carrier is not transmitted as it gets suppressed and is an acronym for Double Sideband Suppressed Carrier and is represented as BW_DSB = 2*f_m-DSB or Bandwidth in DSB-SC = 2*Maximum Frequency DSB-SC. Maximum Frequency DSB-SC is the highest frequency of a band-limited continuous-time signal.

How to calculate Bandwidth in DSB-SC?

Bandwidth in DSB-SC is equal to twice the frequency of the modulating signal. DSB-SC is an amplitude modulated wave transmission scheme in which only sidebands are transmitted and the carrier is not transmitted as it gets suppressed and is an acronym for Double Sideband Suppressed Carrier is calculated using Bandwidth in DSB-SC = 2*Maximum Frequency DSB-SC. To calculate Bandwidth in DSB-SC, you need Maximum Frequency DSB-SC (f_m-DSB). With our tool, you need to enter the respective value for Maximum Frequency DSB-SC and hit the calculate button.
