Question

Consider a $N$-bit plane frame buffer with $W$-bit wide lookup table with $W > N$. How many intensity levels are available at a time ?

• A. $2^{N}$
• B. $2^{W}$
• C. $2^{N+W}$
• D. $2^{N-1}$

Kindly Solve

Answer 1

for N bit plane in the frame buffer,there will be 2^N intensities.to increase it we use look up tables with W bit wide.so we get 2^W intensities.but we can use only 2^N intensities at a time. so the answer will be

Option A
