उत्तर १
Bandwidth : Bandwidth refers to the frequency range over which an equipment operators or the portion of the spectrum occupied by the signal.
उत्तर २
The bandwidth of a signal is defined as the range of frequencies for which the signal is allowed to pass through a medium. The bandwidth of a signal is equal to the difference between the higher or upper-frequency and the lower frequency. It is measured in terms of Hertz(Hz) i.e. the unit of frequency.
Bandwidth is a very important aspect of the communication system. for smooth transmission of signals, a particular range of frequencies i.e. Bandwidth is allocated to a particular signal to avoid the unnecessary overlapping and data loss during transmission.
