Can you make a video lesson on why switch matrix and lamp matrix need to use Diodes because of the strobe signal gets confused with the diodes are shorted. When the Diodes are shorted in one of the ROW the strobe is applied to each column one by one but not understanding if a diode is short why the strobe signal gets confused and errors happen on the matrix tests. When a switch is OPEN the bad diode is shorted the strobe signal doesn't get confused but when a switch is CLOSE the bad diode is shorted the strobe signal gets confused and errors happen in the matrix. I just don't understand what the purpose is for the diode because a GOOD diode allows the strobe signal to flow from column to row/return as well as a BAD diode allows the strobe signal to flow from column to row/return so there is no difference at all logically it doesn't make sense why the matrix will cause errors. The strobe signal looks like on the oscilloscope like a PWM signal or clock signal not sure what is so special about a strobe signal or how its different from a clock signal or PWM.
