Unformatted text preview: ECE130B Jan. 10, 2010 Home work 2 Due date : Jan. 20, 2010 (Wednesday), by 5 p.m. at the home work box. Reading assignment . Chapter 3 of the text book, including both discrete and continuous Fourier series. Square wave . A square wave of period T is denoted by s ( t ) and is given by the formula, s ( t ) = braceleftbigg 1 , if lessorequalslant t mod T < T /2 ,- 1 , if T /2 lessorequalslant t mod T < T , where t mod T is the unique number r between and T that makes t- r exactly divisible by T ; that is, there exists some integer N , such that t = N T + r . Note that N can be a negative integer or even 0. Triangular wave . A triangular wave of period T is denoted by τ ( t ) , and is given by the for- mula, τ ( t ) = 4 T t ′- 1 , if lessorequalslant t ′ < T /2 , 3- 4 T t ′ , if T /2 lessorequalslant t ′ < T , where t ′ = t mod T . Parabolic wave . A parabolic wave of period T is denoted by q ( t ) , and is given by the for- mula, q ( t ) = 8 T 2 t ′ (...
