clear; clc; x=-28; if (x>=0) y=dec2bin(x,6); else y=; end 1. MATLAB The way to compute 2's complement of a negative number 2's Complement: N* = 21-N Ex: - 510 = 24 - 5 = 16 - 5 = 1110 = 1011, MATLAB decimal to binary, "dec2bin() Complete line 7 in twoscomplement.m. Given a decimal integer (either positive or negative), it can be converted into 2's complement binary number. The integer has 6 digits (n=6). Then run it to test if-28 is converted correctly. 2. MATLAB Simulink 2.1 Use one Pulse Generator and one scope. Show the clock signal in the scope. (Sample based, Amplitude=1, Period=2, Pulse width=1, Phase delay=1, Sample time=1). 2.2 Design the binary code for 16 decimal number (0-15) Binary Code Decimal ABCD S S SS 0 0 0 0 0 1 0 0 0 1 2 3 0 0 1 1 0 1 0 0 5 0 1 0 1 6 0 1 1 0 7 6 1 0 0 0 9 1 001 10 11 12 1 1 0 0 13 1 1 0 1 1 Use four pulse generators and one scope to simulate the BCD codes. The waveform should show each of the binary code in the correct order
