- The following binary sequences are stored in two distinct 16-bit memory locations: Q1 A = 10010001 11000111 B = 01111010 11101000 Hint: You can use calculators/tools, but you should show the calculation procedure for each case Find both binary and decimal values of Z=A+B if A, B, and Z are all signed a integers. Find both binary and decimal values of Z=A+B if A, B, and Z are two's complement numbers. If A and B are two Boolean vectors (vectors in which every element is TRUE or C FALSE), find the outcome of the following bit-wise logical operation: (A&&B)||(!A&&!B). What would be the data type and the corresponding value of Z=A+B (written d in Python) if A and B represent two ASCII Strings (Find ASCII table in appendix). If A represent the first two bytes (network prefix) and B represents the last e two bytes (host suffix) of a class B IPV4 address, find the corresponding IP address.When a word is divided by a byte, after division, O a. AL will have quotient, and AH will have remainder O b. AH will have quotient, and AL will have remainder O c. DX and AX will have the quotient, and CX will have remainder O d.

- ASCIIQ5\A) The Amplitude Modulation (AM) is a technique used in communication for transmitting information via radio carrier wave. AM works by varying the amplitude of the transmitted signal in relation to the information being sent. The equations of the carrier signal, the original signal to send, and the modulated signal combining the two signals are respectively: VI-V sin (2nfet) V2=Vm sin (2πfmt) V3-V sin (2nfet)+ Vm sin (2nfmt)* sin (2πfet) Supposing that Vc =Vm=1, fc-20, fm-1. Write a MATLAB program that plots the three signals with single call, the graphs must be contain (desired title, axis labels, annotations, with symbols for color, style, and marker) for each graph. Use the step 0.0025 for the time.Please answer part D only
