Y is smaller than X B. Y is about the same as X C. Y is a larger than X, but not twice as large D. Y is about twice as large as X E. Y is much more than twice as large as X
A majority circuit is a combinational circuit whose output is equal to 1 if the input variables have more 1's than 0's. The output is 0 otherwise. For examples in 3-bit majority circuit with the input variable x, y, z. The output variable is equal to 1 for the decimal numbers 3 (the binary number of 3 is 011), 5 (the binary number of 5 is 101), 6 (the binary number of 6 is 110), and 7 (the binary number of 7 is 111). All these numbers have more 1's than O's. (e.g., 3 in binary has two 1's and one O's; 7 in binary has three 1's, no 0's). Design a 4-bit majority circuit by finding the circuit truth table, the Boolean function, and the logic diagram.
Build a circuit that takes four bits as input: W, X, Y, Z. Treat WX as a 2-bit unsigned binary number, and treat YZ as a second 2-bit unsigned binary number. Your circuit should generate the output corresponding to the product of WX and YZ. You will need 4 bits of output for this problem.For example, if your input was 1011, your inputs correspond to 2 and 3. That product is 6, so your output will be 0110.Create a truth table for this problem, show all k-maps and minimizations, and build the corresponding (minimized) circuit. Use XOR, XNOR, NAND, and NOR as appropriate if it reduces the number of gates used.

Assume we want to find the best match between an EEG signal and a sinusoidal waveform. • EEG sample frequency was 50 Hz. Generate two sin waves with frequency at 14 Hz and 20 Hz. We limit these shifts to 360 sinusoids, each having 1° difference in phase shift. Calculate the Rxx of these two signals at different phases. We will have to shift the sine wave over the EEG signal to find the best match between the two signals.
