Understanding the key characteristics of a waveform is crucial for analyzing and interpreting the signals they represent. These characteristics define the shape, size, and behavior of the waveform and provide valuable information about the underlying signal.

• Amplitude: The amplitude of a waveform represents its maximum displacement from the zero line, indicating the strength or intensity of the signal. Higher amplitudes correspond to stronger signals, while lower amplitudes indicate weaker signals.
• Wavelength: Wavelength is the distance between two consecutive identical points on a waveform, such as the distance between two peaks or two troughs. It is typically measured in units of length, such as meters or centimeters. Wavelength is inversely proportional to frequency, meaning that shorter wavelengths correspond to higher frequencies and vice versa.
• Frequency: The frequency of a waveform refers to the number of complete cycles that occur in a unit of time, typically measured in Hertz (Hz). It represents how rapidly the waveform repeats itself.
• Period: The period of a waveform is the time it takes for one complete cycle to occur. It is the reciprocal of frequency, meaning that period = 1 / frequency. The period is typically measured in seconds.
• Phase: Phase refers to the position of a point in time (an instant) on a waveform cycle. A complete cycle is defined as 360 degrees. Phase differences between two waveforms can indicate time delays or shifts in their relative positions.
• Duty Cycle: The duty cycle of a waveform is the percentage of one period in which a signal is active. It’s most commonly associated with pulse waves, where it indicates the ratio of the pulse’s “on” time to the total period.

Understanding these key characteristics enables you to analyze, interpret, and manipulate signals in a variety of applications.
