-1- Errata for First Edition, First Printing of Stern & Mahmoud, Communication Systems, Analysis and Design My apologies for the errata listed below. These errors will be corrected in the second printing: Page 19, first line under Equation (2.7) – change “Figure 2-9a” to “Figure 2-9”. Page 63, first line in Example 2.13 – change “magnitude spectrum S ( f )” to “magnitude spectrum | S ( f )|”. Page 67, Equation (2.60) – replace the equal sign with the two-headed arrow symbol used in the other equations on this page. Page 68, Equation (2.67) – bracket the first two terms and bracket the last two terms. The corrected equation should be volts/Hz ) ( 2 1 ) ( 2 1 volts 2 1 2 1 ) ( 2 2 + + + + = c c t f j t f j f f S f f S e e f Y c c π π Page 68, Equation (2.70) – Bracket the left-hand side and place a script F (for Fourier transform) in front of the bracket. The corrected equation should be { } volts/Hz ) ( 2 1 ) ( 2 1 2 cos c c c f f f f t f + + = δ δ π Page 119, Problem 3.12, Part e, second line – change “Part c” to “Part d”. Page 135, Equation (4.30) – Remove the absolute value sign and the square in the first integral. The equation should read = = = c c o f f c o o n o f N df N df f G 2 ) ( 2 σ Page 136, Equation at bottom of page – the last term in this equation should read dx e x ) 36 . 0 ( 2 ) 0 ( 5 . 1 2 ) 6 . 0 ( 2 1 π Page 158, First integral on page – replace argument ( it b ) with ( t ). Also, the “b” in the upper limit of the integral should be a subscript. After these two corrections, the integral should read γ s t dt i T iT b b 1 2 1 ( ) ( ) Page 207, Problem 4.8, second line – change units from volts 2 to volts 2 /Hz. Page 208, Problem 4.14, first line – change “Equation (4.31)” to “Equation (4.36)”. Page 230, Definition of a 1 ( iT b ) underneath Equation (4.71 R ) – change “nois” to “noise”.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
