DATA RATE=2*BANDWIDTH*LOG(L BASE 2),
ACCORDING TO THE PROBLEM BANDWIDTH=3KHZ.
AND L=2(BINARY LEVEL).
SO, DATA RATE=2*3*LOG(2 BASE 2).
DATA RATE=6KBPS.

Wifi adapter : 150 kbps.

What is kbps? Discuss the meaning of kbps.

How can it be 6Kbps?

Channel freq = 3000Hz.

That means that It can transmit 3000bits in 1sec.

Hence channel data rate is 3000bits/sec or 3Kbps.

I think it should be 3Kbps.

Since sampling frequency is Fs=2Fm;.

Fs=2*3000Hz=6000Hz;.

Therefore it is 6000 bits per sec=6kbps.

W = 2*B*log2
= 2*3000*1
W = 6000 bps = 6 kbps

so, it is 6000 bits per sec=6kbps.

W = 2*B*log2
= 2*3000*1
W = 6000 bps = 6 kbps

Actually Data rate That is N.

Max data rates Nmax.

We have Nmax=2*B*logL.

Here B=2khz.

L=No.of level=2(as it is binary).

So Nmax=2*3*log2=6(Answer).

Maximum data rate is.

Maximum Capacity in Bits/Second = Bandwidth * Log2 (1 + Signal/Noise).

Where signal = noise = 1. Then apply values.
