Question 7.1: Determine Aol for the following values of f. Assume fc(ol) =...

(a) A_{o l}=\frac{A_{o l(\mathrm{mid})}}{\sqrt{1+f^2 / f_{c(o l)}^2}}=\frac{100,000}{\sqrt{1+0}}=\mathbf{1 0 0 , 0 0 0}

(b) A_{o l}=\frac{100,000}{\sqrt{1+(0.1)^2}}=\mathbf{9 9 , 5 0 0}

(c) A_{o l}=\frac{100,000}{\sqrt{1+(1)^2}}=\frac{100,000}{\sqrt{2}}=\mathbf{7 0 , 7 0 0}

(d) A_{o l}=\frac{100,000}{\sqrt{1+(10)^2}}=\mathbf{9 9 5 0}
