For this circuit I have to find the V_out/V_in ratio and my problem lies on one instance and that is ,
if V1 is negative (for the case V1< Diode on Voltage) all the current flows through the diode and diode acts like constant voltage source which in turn causes some current flow through R_1. My question is ,Why Diode On voltage is the only cause for the current flow through R_1 ? Does V_1 not have any role on causing current flow through R_1 since V1 is in magnitude greater than Diode_On voltage?
