Solution Problems Sequential Circuits Studypool Draw the outputs qa, qb and ins for the digital sequential circuit shown below: solution: here the flipflops are connected in synchronous pattern (common clock to all) and the outputs are connected. at rising edge of first clock, the first flip flop transfers the inpit in to its output qa. Excitation table step 3: derive next state logic t = jq’ kq (design specification) write the state table of the sequential circuit as the following figure. solution: from the circuit we directly get t = x.
Solution Sequential Circuits Analysis Studypool A sequential circuit with two flip flops a and b, two inputs x, y and an output z has the following behavior: a (t 1) = x’.y x (t); b (t 1) = x’.a (t) x (t); z = a. draw the logic diagram of the circuit, list the state table, and draw the state transition graph. In doing the simulation of any sequential circuit, sufficient time must be provided in the clock period for each of the following: all flip flops and inputs to change; the effects of these changes to propagate through the combinational logic of the circuit to the flip flop inputs; and the setup of the flip flops for the next clock edge to occur. Problem : we cannot get r=s=0 (“hold” condition) solution : use ”clock” input. clock is a free running signal with a fixed cycle time or clock period. the duration of “high” and “low” parts of the clock cycle need not be the same. duty cycle : fraction of the period, when the signal is considered active. Electronics questions and answers section on "sequential logic circuits" for placement interviews and competitive exams: fully solved electronics problems with detailed answer descriptions and explanations are given for the "sequential logic circuits" section.

After solving the problems, look at the solutions posted on the course website and categorize your work for each problem on the following scale: completely correct nearly correct, but made a small mathematical or copying error. This document contains 3 practice problems about sequential circuits. the first problem defines a circuit with state equations and asks to draw the logic diagram, state table, and state diagram. the second problem asks to draw the state diagram for a given circuit. Design the synchronous sequential circuit whose state transition table is shown below. use a d ff to implement y0 and a jk ff to implement y1. draw the state diagram of the moore machine which has 2 inputs (x1, x2) and one output z. the output of the machine is determined by the following: the reset input initializes the machine to a 0 output. In contrast to a combinational logic, which is fully specified by a truth table, a sequential circuit requires a state table for its specification. the first step in the design of sequential circuits is to obtain a state table or an equivalence representation, such as a state diagram.
