Addressing of a 32K × 16 memory is realized using a single decoder. The minimum number of AND gates required for the decoder is

A four-variable boolean function is realized using 4 × 1 multiplexers as shown in the figure.



The minimized expression for F(U, V, W, X) is

An 8-bit unipolar (all analog output values are positive) digital-to-analog converter (DAC) has a full-scale voltage range from 0 V to 7.68 V. If the digital input code is 10010110 (the leftmost bit is MSB), then the analog output voltage of DAC (rounded off to one decimal place) is _______ V.

In the figure shown, the output Y is required to be Y = A.B + C̅.D̅. The gates G₁ and G₂ must be respectively.

Select the Boolean function(s) equivalent to x + yz, where x, y, and z are Boolean variables, and + denotes logical OR operation.
