Step 1 of 3 4.026E A function with similar operation can be implemented by more than one way using similar gates. There are three physically different ways to realize the function. Between the variables similar AND operation has to done. By means of associative law, Since we have a single output series connection is needed at the end. Another one is the given gates is similar maximum of two input gates. Therefore, maximum of two gates can be parallel. Hence we can implement the circuit such that Input and output Series implementation. Input Parallel and output series arrangement Few Series Input and some other parallel inputs, output series implementation Step 2 of 3 Implementation of the function F using serial connection of AND gates is shown in Figure 1 V W X Y Z Figure 1: Serial Implementation of Function F Implementation of the function F in parallel input and serial output connection of AND gates is shown in Figure 2. V W Y F Z Figure 2: Parallel input and serial output Implementation of Function F Step 3 of 3 Implementation of the function F in Few Series Input and some other parallel inputs, series output is shown in Figure 3. V W X F Y Z Figure 2: Combined parallel and serial input and serial output Implementation of Function F Hence, three physically different ways of implementation are possible for function F using 4 two input AND gates.
