What are the two types of basic adder circuits?
Let MXI be an inverting 2 : 1 multiplexer whose output is a', when s = 0 and output is b' when s = 1. That is MXI(s, a, b) = s' a' + sb'. What function is the following circuit equivalent to?  
The figure below shows a multiplexer where S1 and S0 are the select lines, I0 to I3 are the input data lines, EN is the enable line, and F(P, Q, R) is the output. F is
VHDL code SUM < = A XOR B Carry < = A AND B where A and B are inputs, represents
Which of the following boolean expression for the logic circuit (shown in this picture) is correct?
ln the circuit shown the device connected to Y5 can have an address in the range:
The propagation delays of the XOR gate, AND gate, and multiplexer (MUX) in the circuit shown in the figure are 4 ns, 2 ns, and 1 ns, respectively. If all the inputs P, Q, R, S, and T are applied simultaneously and held constant the maximum propagation delay of the circuit is
The circuit shown above is to be used to implement the function \(Z = f\left( {A,B} \right) = \overline A + B\). The values of I and J are:
An array multiplier is used to find the product of a 3-bit number with a 4-bit number. How many 4 bits addresses are required to perform multiplication?
For the box shown the output D is true if and only if a majority of the inputs are true. The Boolean function for the output is:
A 3 to 8 Decoder is shown in the figure. Find F(x2; x1; x0)
In the circuit shown in the figure, if C = 0, the expression for Y is
