Consider a simple network protocol for communication between a transmitter and a receiver. You are tasked to design the FSM for the transmitter. The transmitter has two states: idle $($I$)$ and sending $($S$).$ It has two inputs: data ready $($DR$)$ and acknowledge $($ACK$).$ When the transmitter is in the idle state, it waits for the data ready signal. When the data ready signal is received, it moves to the sending state and sends the data. When the acknowledge signal is received, it moves back to the idle state. Design an FSM for the transmitter. Draw the state table and the state diagram.
