Sequential Systems: BCD and Logic Circuits

A circuit that operates based on the current state of its inputs and outputs, where the output is determined by the input at that specific moment.

A circuit that utilizes a series of internal states, where each state is determined by the previous state. It may also be influenced by its input.

A method of representing decimal numbers using binary digits. Each decimal digit is encoded as a 4-bit binary number.

A device that counts in a decimal system, from 0 to 9. After reaching 9, it resets to 0.

A display device that uses seven LEDs arranged to form different segments, which can be illuminated to display numbers and some letters.

An integrated circuit that decodes BCD input signals from a counter to light the correct segments of a seven-segment display.

The process of converting a binary number into its equivalent decimal representation,

A system that allows the repeated execution of a defined sequence of actions or instructions.

An electronic signal that periodically changes its state, typically between high (1) and low (0) levels.

A system that uses a combination of logic circuits and counters to control a sequence of events. The output of the logic circuits is modified by the counter’s state, and the sequence repeats continuously.

A logic gate that inverts the input signal. It produces a logic 1 output when the input is 0, and vice versa.

A logic gate that produces a logic 1 output only when all its inputs are 1.

A logic gate that produces a logic 0 output only when all its inputs are 1.

An electronic device that can be used to create different patterns by illuminating specific segments of the display.

A counter that counts in tens, reaching 10 before resetting to 0.

A tool used to observe and analyze the signals at the output pins of a circuit.

A switch that triggers an output signal when it is momentarily closed or open.

A type of counter with a specific internal wiring that resets after a count of 9, allowing for direct BCD counting.

An electronic signal that changes its state on the rising edge of a clock pulse, typically going from low (0) to high (1).

The process of applying logic gates to specific outputs of a device to create custom characters.

A type of logic gate that produces a logic 1 output only when all its inputs are 0.

A type of logic gate that produces a logic 1 output only when exactly one of its inputs is 1.

A type of counter that counts sequentially, with only one output active at a time.

The output of a logic circuit that triggers a specific action. For example, the output of a logic circuit in traffic lights could control when the traffic light turns red, yellow, or green.

A state in which an output is permanently set to either logic 0 or logic 1.

The state of an output determined by the current state of the input signals and previous output states.

The collection of logic gates used in a circuit to create a specific relationship between the inputs and outputs.

The process of setting the initial condition of a logic circuit or system.

The process of turning on or powering up a system or circuit.

The process of disabling or turning off a system or circuit.
