Question

I only need the calculations for the problem.;There are two methods for designing the nonlinear triangle-to-sine converter.;1. Assume the maximum value of the sine wave is 1.2V (two diode potentials using the constant-voltage model of a silicon diode). Match the slope of the triangle wave v tri (q) to that of the sine wave v s (q) at q = 0, this allows you to compute the maximal value V tri of the triangle wave. Thenmatch the slope of the sine wave to that of the triangle wave multiplied by R b /(R a + R b) when the triangle wave voltage reaches V tri /2. This allows you to compute the ratio of the resistors.;2. Assume that the points of inflection of the piecewise-linear transfer characteristic occur at 29 ? (v s (q) = 0.6V) and 73 ? (v s (q) = 1.2V). Use the first point of inflection to determine the maximal value V tri of the triangle wave and use the change in v s relative to the change in v tri between 29 ? and 73 ? to calculate the ratio of the resistors.
