We need to send 254 kbps over a noiseless channel with a bandwidth of 15 kHz. How many signal levels do we need?
Added by Randall K.
Step 1
In this case, the bandwidth is 15 kHz and the maximum data rate is 254 kbps. 254 kbps = 2 * 15 kHz * log2(L) Dividing both sides by 2 * 15 kHz: 254 kbps / (2 * 15 kHz) = log2(L) Simplifying: 8.47 = log2(L) To solve for L, we need to find the exponent to Show more…
