Question

The number of different symbols a microprocessor with a four-wire data bus can carry is:

Answer 1

Explanation:

The formula for calculating the number of bits or different symbols that can be transmitted with an n-wire data bus is;

Signals = 2 ^n - 1

In the given case, n is 4

Putting the value of n in above formula;

Signals = 2^4 - 1

Signals = 16 - 1

Signals = 15

Hence we can say that 15 different symbols can be carried by a 4 wire data bus in a microprocessor
