WebBandwidth is typically expressed in bits per second (bps). You may see variations of the measurement, including megabits per second (mbps), kilobits per second (Kbps), or gigabits per second (Gbps). You want to have a larger bandwidth, so you can move data faster. A bandwidth of 300 bps will be much faster than a bandwidth of 30 bps. Web1 Answer. That really depends on your requirements and on your exact definition of bandwidth. Telephone range (300 Hz-3.4 kHz) has okay intelligibility but the quality of the …

The voiced speech of a typical adult male will have a fundamental frequency from 85 to 155 Hz, and that of a typical adult female from 165 to 255 Hz. Thus, the fundamental frequency of most speech falls below the bottom of the voice frequency band as defined. However, enough of the harmonic series will be … See more A voice frequency (VF) or voice band is the range of audio frequencies used for the transmission of speech.
