EC-210 Logic & Sequential Circuit Design

The course name for which Assignment 01 focuses on the derivation and design of sequential circuits and counters.

State Table

A descriptive table used to derive the functional behavior and transitions of a sequential circuit.

State Diagram

A graphical representation of the transitions between different states in a sequential circuit.

D Flip-Flops

The specific memory elements, labeled $A$ and $B$, used to design a circuit with a single input $x_{in}$.

$$x_{in} = 0$$

The input condition under which the state of the sequential circuit remains the same.

$$x_{in} = 1$$

The input condition that causes the circuit to transition through the sequence $00 ightarrow 01 ightarrow 11 ightarrow 10 ightarrow 00$.

Four-bit binary ripple countdown counter

A circuit designed to count backwards in binary, which can be implemented using flip-flops that trigger on either the positive-edge or negative-edge of the clock.

Positive-edge trigger

A condition where a flip-flop in the counter changes its state at the rising edge of the clock signal.

Negative-edge trigger

A condition where a flip-flop in the counter changes its state at the falling edge of the clock signal.

BCD ripple counter

A decade counter constructed from a four-bit binary ripple counter equipped with an asynchronous clear and a NAND gate.

Asynchronous clear

A feature used in a four-bit binary ripple counter to reset the count when a specific binary value is detected.

NAND gate

A logic gate used to detect the occurrence of count $1010$ to trigger the asynchronous clear in a BCD ripple counter.
