• A. 2H
• B. 3H
• C. 0
• D. 1

Answer 1

Answer: (A)

2H

Maximum data rate to transmit binary signal from Nyquist theorem is 2H.

Nyquist's Theorem - If the signal has V discrete levels over a transmission medium of bandwidth H, the maximum data rate = 2H log₂ V bits/sec. A noiseless 3-kHz channel cannot transmit binary signals at a rate exceeding 6000 bps (= 2 x 3000 log₂ 2). Workspace.

Nyquist bit rate formula defines the theoretical maximum bit rate. r = 2 X B X log2 L. In this formula, B is the bandwidth of the channel, L is the number of signal levels used to represent data, and r is the bit rate in bits per second.

Data rates are often measured in megabits (million bits) or megabytes (million bytes) per second.
