In the circuit of Fig. 1.27, V,(t) and Vo(t) are voltages (at time ) and R, and R₂ are resistors. There is also an ideal diode that acts as a short circuit when V; is positive and as an open circuit when v, is negative. We view V, and Vo as the system input and output, respectively. (a) Determine an input-output description of this system. (b) Is this system linear? Is it time-varying or time-invariant? Is it causal? Explain your answers.
