Briefly define the term Bandwidth - Width of the spectrum of frequencies that can be transmitted if spectrum=300 to 3400Hz, bandwidth=3100Hz - Greater bandwidth leads to great costs - Limited bandwidth leads to distortion 3. What are the chemical formula Factors for transmittance Media ? - Bandwidth: All another(prenominal) factors remaining constant, the greater the band-width of a signal, the higher the data come in that can be achieved. - transmittance impairments. Limit the distance a signal can travel. - interference: Competing signals in...If you want to get a full essay, order it on our website: Orderessay
