Question: Consider you are asked to design a digital system that controls an electric motor "M". Motor is turned on when logic 0 is applied and turns off when logic 1 is applied. Two identical photo sensors, "S1" and "S2" produce logic 1 when light falls on them and provide logic 0 when light does not fall on them. Motor is to be controlled in such a way when light falls on both sensors, motor turns on. When light falls on S1 only, motor turns on. When light falls on S2 only motor turns off. Motor turns off when both sensors do not receive any light.

Transcribed Image Text:Question: Consider you are asked to design a digital system that
controls an electric motor “M". Motor is turned on when logic 0
is applied and turns off when logic 1 is applied. Two identical
photo sensors, “S1" and "S2" produce logic 1 when light falls on
them and provide logic 0 when light does not fall on them. Motor
is to be controlled in such a way when light falls on both sensors,
motor turns on. When light falls on S1 only, motor turns on. When
light falls on S2 only motor turns off. Motor turns off when both
sensors do not receive any light.
