[논리회로실험] 실험 4. Multiplexer & Demultiplexer 결과보고서

문서 내 토픽

1. Multiplexer

이번 실험에서는 IC칩을 여러 개 이용하여 Multiplexer을 구성해보고 다음으로 Multiplexer의 역할을 하는 단일칩을 이용하여 회로를 구성한 후 두 결과값을 비교해보았다. Multiplexer는 여러개의 입력으로 하나의 출력을 나타내는 역할을 하며, 컴퓨터에 여러개의 단말기가 연결되었을 때 단말기 연결을 하나로 묶어서 비용도 절감하고 관리의 편리성을 증가시키는데 사용되고 있다.
2. Demultiplexer

실험 2에서는 AND GATE와 NOT GATE로 Demultiplexer를 구성하였고 S0과 S1의 입력 값을 변경해주며 다이오드를 통해 출력값을 확인함으로 Demultiplexer의 회로가 어떻게 작동하는지 직접 확인해보았다. Demultiplexer는 Multiplexer와 반대의 역할을 하며, 인터넷의 수신과정에서 사용되고 있다. 즉 외부의 신호를 하나의 단말기로 넣어주는 역할을 한다.
3. IC 칩 구성

실험 1과 실험 2에서는 여러 개의 IC칩을 이용하여 Multiplexer와 Demultiplexer를 구성하고, 단일칩으로 구성한 회로와 결과를 비교해보았다. 여러 개의 IC칩을 사용하여 구현한 회로와 단일칩으로 구현한 회로에는 성능적인 차이가 있을 것으로 예상되었다. 예를 들어 단일 IC칩의 입장에서 IC 칩의 개수 차이로 인한 브레드보드의 공간적인 이득이나, 여러 IC을 통과하여 출력을 도출하는 것과 하나의 IC만으로 출력을 나오게 하는 시간적인 이득이 존재할 것이라 생각했다.

1. Multiplexer

Multiplexers are essential components in digital electronics and computer systems. They are used to select one of several input signals and route it to a single output. This allows for efficient data transmission and processing, as multiple signals can be transmitted over a single line. Multiplexers are commonly used in applications such as data communication, signal processing, and memory management. They provide a flexible and cost-effective way to manage and control the flow of information in complex systems. The ability to select from multiple inputs and direct them to a single output makes multiplexers a versatile and widely-used component in modern electronics and computing.
2. Demultiplexer

Demultiplexers are the counterpart to multiplexers and play a crucial role in digital electronics and computer systems. They are used to take a single input signal and route it to one of several outputs, effectively distributing the input to the appropriate destination. Demultiplexers are essential for tasks such as address decoding, memory addressing, and control signal distribution. They allow for efficient resource utilization by enabling the selective activation of specific components or circuits based on the input signal. Demultiplexers are particularly useful in applications where multiple devices or subsystems need to be controlled or accessed independently, such as in memory management, peripheral device selection, and digital logic design. The ability to direct a single input to one of many outputs makes demultiplexers a fundamental building block in the design and implementation of complex digital systems.
3. IC 칩 구성

The internal structure and composition of integrated circuit (IC) chips are fascinating and complex. IC chips are the backbone of modern electronics, powering a wide range of devices and systems. At the core of an IC chip are transistors, which are the fundamental building blocks that enable the processing and storage of digital information. These transistors are arranged in intricate patterns and interconnected through a network of conductive layers and insulating materials to form the various functional components of the chip, such as logic gates, memory cells, and input/output interfaces. The miniaturization and high-density integration of these components within the chip allow for remarkable computational power and capabilities in a compact form factor. The precise fabrication processes, including lithography, doping, and thin-film deposition, are crucial in ensuring the reliable and efficient operation of IC chips. Understanding the internal structure and composition of IC chips is essential for designing, manufacturing, and optimizing these essential components that drive the technological advancements we rely on in our daily lives.
