Hi, I have a precision op amp and a sinusoidal input voltage at the non-inverting input (as in the figure) and am required to find the voltage waveforms at X and Y. According to my knowledge, when Vin is positive, Vout is equal to Vin and hence the graph for Y should be the same as for Vin and since X is being taken from that voltage, its waveform should be the same too, but with a lower amplitude. When Vin is negative, Vout (and hence X and Y) is zero. So what I essentially get is sinusoidal wave for parts where sine(x) is positive and zero elsewhere. Is this approach right or am I missing something?
