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
When analog voice signal converts into digital signal the bandwidth needs 64kbps. Why?
PCM technique is used to convert analog voice signals into digital. In PCM the analog frequency is first sampled and then converted into binary bits. Each samples are taken as 8bits long. Basic communication theory requires that a minimum sampling rate of twice the frequency of the signal to be sampled will result in an accurate representation of the original signal.Human voice can have max 4000hz frequency, therefore sampling rate should be 8000 samples/sec.Which implies required bit rate for transmitting voice is 8000*8 = 64000 bits/sec = 64kbps.
What are the 5 voice qualities?

How is the data rate for PCM digital voice signals 64 Kbps calculated?
The data rate for Pulse Code Modulation (PCM) digital voice signals is calculated using the formula: Data Rate = Sampling Rate × Bits per Sample. For standard voice applications, the sampling rate is typically 8 kHz (samples per second), and each sample is represented by 8 bits (1 byte). Thus, the calculation is 8,000 samples/second × 8 bits/sample = 64,000 bits per second, or 64 Kbps. This rate is sufficient to capture the frequency range of human speech effectively.
How many bits are in a conventional PCM voice sample?
8
What you will become if you take pcm with c plus plus?
A bit of sound, depending how much PCM you take.
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.
A 2MB PCM has how many voice channels?
There are 32 channels in total. Out of which 31 are voice channels and 1 is signalling channel
What bit rate are sacd?
Super Audio CDs (SACDs) typically use a bit rate of 1.4 Mbps for their DSD (Direct Stream Digital) audio format, which is significantly higher than standard CDs. This allows for a higher resolution audio experience, supporting up to 5.1 channels of surround sound. In comparison, standard CDs operate at a bit rate of 1.411 Mbps using PCM (Pulse Code Modulation). The high bit rate of SACDs contributes to their enhanced audio fidelity.
What is the sampling rate for PCM if the Frequency ranges from 1000 to 4000 Hz?
>8000hz
How many discrete sample levels does 4bit PCM have?
A 4-bit Pulse Code Modulation (PCM) system can represent (2^4) or 16 discrete sample levels. This is because each bit can have two possible values (0 or 1), and with four bits, the total combinations amount to 16. Thus, a 4-bit PCM can encode signals into 16 different amplitude levels.
How do you convert WAV mono files to 8K 16 Bit pcm format?
