WebbThe proportional band is defined as the amount of change in input (or deviation), as a percent of span, required to cause the control output to change from 0% to 100%. Because a narrower proportional band gives greater output change for any given WebbThe proportional bandwidth instrument consists of a series of relatively broadband ﬂlters with upper and lower half-power frequencies satisfying the relationshipfu=f‘= constant. Each bandwidth, being proportional to the center frequency, increases with increasing fre- quencies with contiguous bands. 1. At a SNR of 0 dB (Signal power = Noise power) the Capacity in bits/s is equal to the bandwidth in hertz. 2. If the SNR is 20 dB, and the bandwidth available is 4 kHz, which is appropriate for telephone communications, then C = 4000 log2(1 + 100) = 4000 log2 (101) = 26.63 kbit/s. Note that the value of S/N = 100 is equivalent to the SNR of 20 dB. fotoline windows 10 64bit
