NPUT (CL) 1) INPUT: X1: X1: X2: X2: x3: 2) 5. Consider the circuit below, consisting of three R-S flip-flops connected as T-flip-flops. Required: 1) Draw in the indicated spaces below, the diagrams of the outputs 21, 22, 23, as well as of T1, T2, T3. Important: The outputs 21, 22, 23 have all initial values of 0, which gives their complements, 1, 2, 3 initial values of 1. 2) Describe in one sentence what this circuit could be used for.
