A combinational circuit has four inputs (A,B,C,D), which represent a binarycoded-decimal digit. The
circuit has two groups of four outputs - S,T,U,V(MSB digit) and W,X,Y,Z.(LSB digit)Each group
represents a BCD digit. The output digits represent a decimal number which is five times the input
number. Illustrate the minimum expression for all the outputs?
- if the voltage across an element is 8V and the current i entering the positive terminal is as shown, find the power delivered to the element at t=7 ms and the total charge and total energy delivered to the element between 1 and 10 ms.
