Lab 11: Complex Numbers Tims
MATLAB code: rectangular to polar polar to rectangular INTRODUCTION The following labs specializes in complex numbers in TIMS which is a software used throughout the semester. Complex numbers are mathematical entities of the form a + bi, where "a" and "b" are real numbers, and "i" is the imaginary unit (defined as the square root of -1). They play a crucial role in signals and systems because they provide a convenient and powerful way to represent sinusoidal signals and manipulate their properties. The use of complex numbers simplifies mathematical operations, such as addition, subtraction, multiplication, and division, making it easier to analyze and describe the behavior of signals in both time and frequency domains. PROCEDURE PRELAB To refresh the student a prelab assignment is required. Vectors converted to polar form and graphed in figure 1. 3+j4 = 5 angle 53 deg 3-j4 = 5 angle -53 deg -3+4j = 5 angle 127 deg -4-4j = 5 angle 233 deg Figure 1: C...
