The bandwidth of a Pulse Code Modulation (PCM) signal is determined by the Nyquist theorem, which states that the minimum sampling rate must be at least twice the highest frequency present in the analog signal. Therefore, if the highest frequency of the analog signal is ( f_m ), the required sampling rate is ( 2f_m ). The bandwidth of the PCM signal will typically be twice this sampling rate, resulting in a bandwidth of approximately ( 4f_m ). In practice, additional factors like filter roll-off may affect the actual bandwidth requirements.

Compare and contrast PCM and DM?
Pulse Code Modulation (PCM) and Delta Modulation (DM) are both methods of encoding analog signals into digital form. PCM samples the amplitude of the analog signal at regular intervals and quantizes these values into discrete steps, making it more accurate and less prone to distortion. In contrast, DM encodes the difference between successive samples, resulting in a simpler implementation but potentially lower fidelity and higher sensitivity to noise. While PCM generally offers better sound quality and requires more bandwidth, DM is more efficient in terms of data rate but may introduce quantization error.
What is a sentence for bandwidth?
The lawyer did not have the bandwidth to handle another case. The bandwidth was more than adequate to transmit the data quickly.
Where online can one find bandwidth monitoring tools?
Bandwidth monitoring tools are available online from many different sources. Some software that one can download for bandwidth monitoring include Manage Engine and Softperfect. There also have free bandwidth monitoring programs, include "WFilter" and "PRTG".
How can you use bandwidth in a sentence?
To use applications remotely requires a lot of bandwidth, which is only really available from a broadband connection.My ADSL bandwidth is low, so I can't download files very quickly.
Does O.co offer hosting unlimited bandwidth?

Why is the bandwidth of DPCM is greater than PCM?
in pcm entie sample is sent.. where as in dpcm the difference between the predicted value and the original sample is sent which will be smaller when compared rto the original sample..

What is the relationship between quantisation noise and bandwidth in pcm systems?
Quantization noise is a model of quantization error introduced by quantization in the analog-to-digital conversion(ADC) in telecommunication systems and signal processing.
