Design a multiple-output logic circuit whose input is a BCD digit and whose outputs are defined as follows: 1f: Detects input digits that are divisible by 4, 2f: Detects numbers greater than or equal to 3, 3f: Detects numbers less than 7. Write a Verilog and/or VHDL model of the circuit. Also, realize the circuit using NAND gates.

Refrigerant-134a enters the compressor of a refrigerator as superheated vapor at 0.14 mpa and -10°c at a rate of 0.05 ka/s and leaves at 0.8 mpa and 50°c. the refrigerant is cooied in the condenser to 0.72 mpa and 26'c. it is then throttled to 0.15 mpa. sketch the t-s diagram for the system and evaluate: 6) the rate of heat removai from the refrigerated space (kw), it) the power input to the compressor (kw), ii) the isentropic efficiency of the compressor (%), and iv) the cop of the refrigerator.
