![]() This is the fundamental property of bandwidth. Any band with a certain width may convey the same amount of information as where the bar is situated in the frequency spectrum. Human hearing ranges from 20 Hz to 20 kHz, whereas a dog’s hearing ranges from 50 Hz to 46 kHz. Contemporary telephones function with a bandwidth of 2800 Hz because the frequency range of 300 Hz to 3100 Hz is adequate for conveying sounds or speech.ĭue to the numerous instruments and range of pitches, music transmission requires a signal bandwidth of 20 kHz. One such collection of frequencies microwaves is utilized for a different function than other sets. ![]() More significant frequencies can carry incredible energy and information, but they are less effective and cannot be communicated over long distances. The lower frequencies, which undergo less attenuation over long distances, are employed for long-distance communication. Fortunately, a vast spectrum of frequencies is ready to listen to our request. The data can be in several formats, including voice, video, photo, word document, etc., another aspect at work. Depending on the mode selected, this information is transmitted at a specific frequency by wire or air. We share information in bits with the recipient when we send an email. ![]() A communication system’s goal is to convey data from a transmitter situated in one location to a receiver typically placed distant from the transmitter. What does a signal’s bandwidth refer to? A frequency range within a continuous collection of frequencies is called bandwidth. ![]()
