In this video, electrical engineer Barron Stone constructs a square wave by adding together multiple sine waves with different frequencies and amplitudes. Learn about signal bandwidth and why not having enough bandwidth can adversely affect the shape of a
- [Voiceover] One of the main reasons for thinking about…signals in the frequency domain…is to consider the signal's bandwidth,…which is the range of frequencies that make it up.…The term bandwidth can also refer to the range of…frequencies that can be transmitted through a circuit.…In some cases, a circuit might be intentionally designed…as a filter to limit a signal's bandwidth by removing…certain frequencies from the signal…while allowing others to pass through.…In other cases the bandwidth of a signal…might be naturally limited by physical characteristics…of the circuit it's passing through.…
Bandwidth is typically measured in hertz,…and it represents the difference in hertz…between the upper and lower frequencies within a range.…To understand why it's important to consider…the bandwidth of any circuit that will transmit a signal,…let's take a closer look at the frequency components…that make up one of the most common types of signals,…a square wave.…Square waves commonly occur in digital circuits…where signals periodically switch between two voltages,…
