$2.$ b$.$ Three Devices $($D$1,$ D$2,$ and D$3)$ are connected to a central arbiter in Daisy$-$chain arbitration with $3-$wires, with D$1$ is the highest priority and D$3$ is the lowest one. The Requests of these devices are started as shown. Show on the timing diagram the sequences of gaining the bus for each request, assuming that T is enough for arbitration and complete cycle time of each device. Show when the Request signal of each Device will be inactive.

Complete the Schematic diagram shown below for this arbitration and show how these devices are connected to the bus master and the direction of each signal.
