a) Use the constant voltage drop model for the diode and determine the input / output ratio (Vout x Vin), equations. Vdon = 0.7V, rz = 0Ω, Vz = 3V and R = R1 = R2 = 1000Ω.
b) Draw the Vout x Vin graph. Highlight the slope coefficients of the lines and the coordinates of the points where the slope changes occur.
