Question:
a) Draw the block diagram and explain the design of the system.
b) Construct the schematic circuit and explain each of the circuit design.
c) Draw the output result of each modules circuit.
d) Sketch the layout of the system.
Design an Electronic Tachometer System using counters, latched outputs, and multiplexed displays. The design will combine known input and output as well as digital devices that will indicate the angular velocity of a shaft measured in rpm (revolutions per minute). A 4-digit BCD counter is the heart of the system. The idea is count the number of input pulses from the Hall-effect sensor in 1/10 of a minute and accumulate that count for a given time such as 1 minute, 10 minutes, 30 minutes and 1 hour. The counter would be turned on and count upward in BCD for one hour and then turned off The count held in the four-digit BCD counter would then be decoded, and the seven- segment display would present the shaft speed in rpm. The seven-segment displays would present the latest accumulated count from the BCD counters and the Os place always be considered a 0.
