If I am using PWM to light up LED lights, and I want slow and gentle dimming lights- kind of like the ones that light up real slow that people use for romantic dates. With regards to PWM, the frequency of the pulses relates to how quickly/slowly, we can get the pulse to the output device. Using this technique, we can simulate an analog output using a digital output. Pulse width modulation or pulse duration modulation is a technique where we vary the width of a square pulse to control the power supplied to any connected device.
