Please help me to find out, what is the bandwidth in (kHz) of an AM (SSB-SC) signal with a carrier frequency of 941 kHz and a baseband signal that has frequency components from 20 Hz to 19 kHz? thanks
Perfect!qduy said:Single-sideband suppressed-carrier (SSB-SC) is a refinement of amplitude modulation that more efficiently uses electrical power and bandwidth.
Hi Bbqonion, welcome to Physics Forums.Bbqonion said:I did an experiment in school to find the bandwidth of an amplifier with negative feedback.
I cound not get a high enough input voltage with the signal generator. Is a terminal of the signal generator supposed to be connected to the earth?
By "the earth" do you mean that big asteroid sort of thing inhabited by simians? Then the answer is no. Not directly.... supposed to be connected to the earth?
An AM (SSB-SC) signal is a type of amplitude modulation where the carrier signal is suppressed, leaving only the upper or lower sideband. This results in a more efficient use of bandwidth compared to traditional AM signals.
The bandwidth of an AM (SSB-SC) signal with a carrier frequency of 941 kHz is 19 kHz, as only one sideband is transmitted and the bandwidth of each sideband is half of the original bandwidth.
The bandwidth of an AM (SSB-SC) signal is calculated by subtracting the carrier frequency from the highest frequency in the signal, and then multiplying by two to account for both the upper and lower sidebands. In this case, the calculation would be (19 kHz - 941 kHz) x 2 = 19 kHz.
The purpose of using a 20 Hz to 19 kHz bandwidth for an AM (SSB-SC) signal is to allow for the transmission of a wide range of frequencies, including the audio frequencies that make up human speech and music. This allows for clear and accurate reproduction of sound signals.
The bandwidth of an AM (SSB-SC) signal is narrower compared to traditional AM signals, which typically have a bandwidth of 20 kHz. It is also narrower than FM signals, which have a bandwidth of up to 200 kHz. This means that AM (SSB-SC) signals require less bandwidth and can be used more efficiently in the frequency spectrum.
