design a combinational-logic subsystem as part of a larger system that makes change from quarters. There is alarge reservoir of dimes and another one of nickels. There are also two binary counters that keep track of the number of dimes andnickels in each (these are outside your subsystem, and you won'tneed to design them-but you will need them as inputs). Your subsystem needs to work as follows. It takes the low-order bits ofthe dimes counter and the nickels counter, and generates the numberof dimes to give as change and the number of nickels. In general,dimes should be given before nickels, e.g., if there are at leasttwo diis left, these should be given with a singlenickel, rather than five nickels. There is definitely a possibilitythat no change can be given before the reservoirs are (almost)exhausted of coins, and a "no change available" sign should be illuminated.
(a) Identify your inputs andoutputs.
(b) Specify the encoding of youroutputs: what do they mean?
(c) Develop the minimizedgate-level implementation using the K-map method.
