# triangle signal

Triangular signals are one-time or periodic harmonic signals with constant rising and falling slopes. If the rising signal slope corresponds to the falling signal slope, then the duty cycle

is 50 %. The period duration

is madeup of the rise and fall times. If the duty cycle is changed, the triangular signal becomes a sawtooth signal

with a rising or falling sawtooth function.

Triangular signals consist of the sinusoidal fundamental and even and odd sinusoidal harmonics. The amplitudes of the harmonics are in the ratio 1/nexp2, where "n" corresponds to the harmonic. For example, the amplitude of the 3rd harmonic is 1/3exp2, which is 1/9 of the fundamental, that of the 5 harmonics is 1/5exp2, which is 1/25 of the fundamental, and so on.
