How Do You Calculate the Average Value of a Square Waveform?

[Sueyeeyab]

Homework Statement

Alpha=0.91 ,beta=2.92, T0=0.91

Homework Equations

The value of a0 for the square waveform

The Attempt at a Solution

1/T0 * area = 1/0.91*(2.92-0.91)*0.91

T0 has nothing to do with it.
(I assume a0 is the first coefficient of the cosine Fourier series.)

Expressions with brackets must be written unambiguously, viz.,

(1/T0) * area = (1/0.91)*(2.92-0.91)*0.91[/size]

To determine the average area, you must first sum the individual areas (or use a method which is equivalent). There are two rectangular areas to sum.
