Figure shows the internal schematic of a TTL AND-OR-Invert (AOI) gate. For the inputs shown in Figure, the output Y is

11001, 1001 and 111001 correspond to the 2’s complement representation of which one of the following sets of number?

The range of signed decimal numbers that can be represented by 6-bite 1’s complement number is

In the modulo-6 ripple counter shown in the figure, the output of the 2-input gate is used to clear the J-K flip-flops. The 2-input gate is
