Air pressure in a tank is measured and the related digital value is transmitted to the control room using signed two's complement form along with an even parity scheme. Tank's digital air pressure value is considered a binary number that varies between (-3) bar to (+3) bar. The received binary number along with the parity is checked in control room. If there is a negative pressure then a yellow LED should turn on to indicate the low pressure. If the tanks pressure is above (+1) bar a green LED should turn on to indicate an acceptable pressure. If the parity shows that a wrong value is received then a red LED should turn on indicating a transmission error. - Give a truth table that will define the outputs for three LEDs. - Write the simplest expression you can for all LEDs. - Draw a circuit to implement your design.

Transcribed Image Text:Air pressure in a tank is measured and the related digital value is
transmitted to the control room using signed two's complement form along with an even
parity scheme. Tank's digital air pressure value is considered a binary number that varies
between (-3) bar to (+3) bar. The received binary number along with the parity is checked
in control room. If there is a negative pressure then a yellow LED should turn on to indicate
the low pressure. If the tanks pressure is above (+1) bar a green LED should turn on to
indicate an acceptable pressure. If the parity shows that a wrong value is received then a
red LED should turn on indicating a transmission error.
