A triangular wave or triangle wave is a non-sinusoidal waveform named for its triangular shape. It is a periodic, piecewise linear, continuous real function.. Like a square wave, the triangle wave contains only odd harmonics.However, the higher harmonics roll off much faster than in a square wave (proportional to the inverse square of the harmonic number as opposed to just the inverse).

Continuous-wave radar (CW radar) is a type of radar system where a known stable frequency continuous wave radio energy is transmitted and then received from any reflecting objects. Individual objects can be detected using the Doppler effect, which causes the received signal to have a different frequency from the transmitted signal, allowing it to be detected by filtering out …

Sine Wave - Paul Cowan “If you want to find the secrets of the universe, think in terms of energy, frequency and vibration.” ~ Nikola Tesla Definition A sine wave, or sinusoid, is a mathematical curve that describes a smooth periodic oscillation. A sine wave is a continuous wave. It is named after the trigonometric…
