Скачать или смотреть Introduction to Electronics: Filters - What is a first order filter

This video is part of the "Introduction to Electronics: Filters" course, created to help beginners understand the principles and applications of electronic filters through hands-on projects. You will explore essential topics like RC and RL filters, cutoff frequency, phase shift, Bode plots, and how filters are used in audio, sensors, and power supplies.

In this video, we answer the question: What is a first-order filter? You will learn that a first-order filter uses one reactive component, either a capacitor or an inductor, combined with a resistor to control how a circuit responds to different frequencies. These filters introduce a gradual signal roll-off beyond the cutoff frequency and are widely used due to their simplicity and effectiveness. We cover key concepts such as time constants, cutoff frequency, transfer function, and how first-order filters compare to higher-order alternatives.
