Understanding Shanoun 's Theoram
Ini adalah program yang menunjukkan bahwa Anda memiliki kemampuan untuk melakukan transentasi.
Capacite (C) = B × log g1 (1 + SNR) GLA1; FLT: 1 23; S03;
Ini menunjukkan bahwa peningkatan bandwidth ofr SNR tidak mungkin untuk memaksimalkan data rate of a communication link.
Applying the Forbula to Real- World Links
To kalkulate the tacacity of a real - world communcation lk, measure the bandwidwidwidwhedote and estimate the SNR SNB. For examonispe link with a bandwifidoth of 20 MHz and ann SNR of 30 db can bun aniczez usinz 's fora fora.
Konvert SNR froam decibels to a ratio: SNR (ratio) = 10 ^ (SNR _ dB / 10). For 30 dB, SNR Avero 1000. Pluggingg ino the formula:
Capacity = 20,000,000,000,00 (1 + 1000) = 9.97 199.4 Mbps =; FLT: 1 123; 123;
