Q. Figure below depicts a part of a factory that makes bubble gumballs. The gumballs travel on a conveyor that has three associated sensors s1, s2, and s3. The sensor s is connected to a scale that weighs each gumball, and if a gumball is not heavy enough to be acceptable then the sensor sets s, = 1. Sensors s2 and s3 examine the diameter of each gumball. If a gumball is too small to be acceptable, then s2 = 1, and if it is too large, then s3 = 1. If a gumball is of an acceptable weight and size, then the sensors give s1 = s2 = S3 = 0. The conveyor pushes the gumballs over a "trap door" that it used to reject the ones that are not properly formed. A gumball should be rejected if it is too large, or both too small and too light. The trap door is opened by setting the logic function f to the value 1. %3D - gumball A. PAL realization. B. FPGA with VHDL code.

Q. Figure below depicts a part of a factory that makes bubble gumballs. The gumballs
travel on a conveyor that has three associated sensors s1, S2, and s3. The sensor s, is
connected to a scale that weighs each gumball, and if a gumball is not heavy enough to
be acceptable then the sensor sets s1
each gumball. If a gumball is too small to be acceptable, then s2 = 1, and if it is too
large, then s3 = 1. If a gumball is of an acceptable weight and size, then the sensors
give s1 = s2 = S3 = 0. The conveyor pushes the gumballs over a “trap door" that it
used to reject the ones that are not properly formed. A gumball should be rejected if it
is too large, or both too small and too light. The trap door is opened by setting the
logic function f to the value 1.
