{13.4} In the diode shown, the diodes are ideal except that each is modeled by a voltage source of 0.5V in series with a (diode) resistance of rd=20, when forward biased. A sinusoidal signal Vs with input impedance Rs=100 is connected to the diode circuit. Determine the maximum value of Vs such that Vo remains sinusoidal, with no distortion. Also, find the amplitude of the output signal Vo.
