we need to send 254 kbps over a noiseless channel with a bandwidth of 15 khz. how many signal levels do we need

The level of the signal is 353.85

Explanation:

Data rate determines the speed of the data transmission.

The data rate depends on the following factors

The data is transmitted either from a noiseless channel or a noisy channel.

The given quality of the channel in the question is noiseless.

Use the following formula to calculate the signal levels

Bit rate = 2 x bandwidth x ( signal level )

where

Transmitted Data = 254 kbps = 254,000 bps

Bandwidth = 15 khz = 15,000 hz

Placing values in the formula

254,000 = 2 x 15,000 x ( L )

254,000 = 30,000 x ( L )

254,000 / 30,000 = ( L )

8.467 = ( L )

L =

L = 353.85 levels
