5. Your friend D. G. Tully is very excited because she figured out a way to transmit digital information wirelessly via a light signal. However, she does not know digital circuits so she comes to you for help. She shows you the circuit in figure 7. The circuit contains a Light dependent Resistor (LDR), which changes its resistance from Row when light is shone on it and Rhigh in the dark. V DD R₁ T {RL (a) Configuration A Vo V DD J ww Ri V DD (b) Configuration B Figure 7: LDR Receiver (a) Which circuit configuration will give you a non-inverting output i.e the output of the inverter, Vo goes high when the light is bright and low when the light level is low and which one will give you the inverting output?
