Bandwidth is defined as a frequency span - the difference between a high frequency and a lower frequency. For the low end voice it depends if its male bass bariton tenor or female alto and soprano. A bass voice goes down to 100 Hz. The harmonics go up to 15 kHz. So the bandwidth for voices is arround 15 kHz.

You would utilize a VoIP adapter in the conversion of analog voice signals into digital IP packets. These adapters also have the ability to convert digital IP packets into analog voice streams.
Bandwidth is the measure of range or band of frequencies that a channel or path can handle at a maximum rate. whereas, throughput is the average rate of successful message delivery over a communication channel. and Goodput is simply the changing in throughput rate.

The transmission bandwidth refers to the range of frequencies that are being transmitted from one point to another. The channel bandwidth on the other hand refers to the frequencies of a given channel.
I'm afraid you will need to specify on what exactly are you referring to. We could be talking about a radio channel bandwidth, a computer data transfer channel bandwidth or even a radio communications channel bandwidth. It is difficult to tell with the narrow question you posed.
Low pass channel or medium with the bandwidth that starts from zero.Band pass channel has the bandwidth that does not start from zero.
The coherence bandwidth of a wireless channel is the range of frequencies that are allowed to pass through the channel without distortion.
Advantage of Analog Communication: 1)Transmission bandwidth required is less. 2)No need of synchronization.
distorttion
Measurement of the capacity of a communications signal. For digital signals, the bandwidth is the data speed or rate, measured in bits per second (bps). For analog signals, it is the difference between the highest and lowest frequency components, measured in hertz (cycles per second). For example, a modem with a bandwidth of 56 kilobits per second (Kbps) can transmit a maximum of about 56,000 bits of digital data in one second. The human voice, which produces analog sound waves, has a typical bandwidth of three kilohertz between the highest and lowest frequency sounds it can generate.
The two types of communication channel are analog and digital communication channel. An analog channel uses continuously varying (analog) electrical signals while a digital one uses discrete signals.
In the Narrow-band channel the signal see the channel as a flat channel , and the signal pass the channel without any type of cut . In the other hand the signal that passes through the wide-band channel see the channel as a frequency selective channel and cut values from the signal . I mean that if the bandwidth for the signal is lager than the bandwidth for the channel then, the channel is a wide-band channel, and if the bandwidth for the signal is smaller than the bandwidth for the channel then the channel will be a narrow-band channel .
