Elwood is a dog who has a very simple behavior. He barks whenever the doorbell rings. Also, he will bark if the phone rings provided that his human, Elmer, is snoring.
Let's design a circuit for Elwood. His input sensors (bits) are:
A value of 1 indicates ringing. A value of 0 indicates no ringing. | |
A value of 1 indicates ringing. A value of 0 indicates no ringing. | |
A value of 1 indicates snoring. A value of 0 indicates no snoring. |
Draw the circuit which demonstrates Elwood's barking behavior:
