• Sawtooth waves are known for their use in music. The sawtooth and square waves are among the most common waveforms used to create sounds with subtractive analog and virtual analog music synthesizers. • Sawtooth waves are used in switched-mode power supplies. In the regulator chip the feedback signal from the output is continuously compared to a high frequency sawtooth to generate a new duty cycle PWM signal on the output of the comparator. WebThe sawtooth wave is defined to be –1 at multiples of 2 π and to increase linearly with time with a slope of 1/ π at all other times. x = sawtooth (t,xmax) generates a modified triangle wave with the maximum location at each period controlled by xmax. Set xmax to 0.5 to …
