Why PCM sampling time at 125 m sec?
PCM (Pulse Code Modulation) sampling time of 125 microseconds is typically associated with a sampling rate of 8,000 samples per second. This rate is sufficient for capturing audio signals within the frequency range of human hearing, which is generally up to 20 kHz, in accordance with the Nyquist theorem. By sampling at this rate, the system effectively captures the necessary signal details while minimizing aliasing and ensuring good audio quality.
What is the bandwidth of N bit binary coded PCM?
It is same as the bit rate. B = R = nfs where n= no of bits fs= sampling frequency R= bit rate
What numbers on the pcm do you need to match up to replace it?
We need at least two numbers on the PCM to match and replace it.
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..
Which Coding system is used in digital telemetry?
PCM (Pulse Code Modulation)

What is the sampling rate for PCM if the Frequency ranges from 1000 to 4000 Hz?
>8000hz
What uis the sampling rate for PCM if the Frequency ranges from 1000 to 4000 Hz?
As we know that the sampling rate is two times of the highest frequency (Nyquist theorm) Sampling rate=2 Nyquist fs=8000hz/8khz
What sampling rate from a sound card would you require if you want to be able to record CD sound quality?
The standard CD is two-channel 16-bit PCM encoding at a 44.1 kHz sampling rate per channel.
What are the processes required to perform PCM?
Performing Pulse Code Modulation (PCM) involves three main steps: sampling, quantization, and encoding. Sampling is the process of measuring the analog signal at regular intervals. Quantization involves rounding the sampled values to a limited number of discrete levels. Encoding then converts the quantized values into a binary format for transmission or storage.
What is the bandwidth of N bit binary coded PCM?
It is same as the bit rate. B = R = nfs where n= no of bits fs= sampling frequency R= bit rate
The main advantage of PCM system is?
The main advantage of PCM (pulse code modulation) system is its robustness in transmitting and storing digital audio signals while maintaining high fidelity. PCM provides accurate representation of the original analog signal by sampling and quantizing it into binary code, making it less prone to distortion and noise compared to analog transmission methods.
How do you time a Saturn 1.9l engine?
Timing is controlled by the PCM .
How do you time a 2001 Ford Escape?
Timing is pre-set by the PCM
Where is pcm on a Lincoln cont?
THE PCM IS ON THE PSSENGER FIREWALL THE PCM IS ON THE PSSENGER FIREWALL
What would cause tbi injectors to stay open all the time?
A grounded signal wire from pcm, faulty pcm, or faulty injector are the only possible causes.
How do you change the time in a 2003 Chevy Malibu?
timing is set by pcm, at factory!!
