![]() ![]() By taking the inverse of the frequency (1/f) we can find the period. ![]() For these calculations we need a slightly different descriptor for the speed of the waves. The frequency of a sound wave (Or any wave for that matter) is the number of times the signal cycles (goes up and back down) in a second and is expressed in Hz. When working with synthesizers you’ve probably heard signals described in terms of frequency. To keep things simple today we will work with a 50% duty cycle meaning the signal will be high for the the same period it is low. It follows that we should be able to apply our step equation to the steps in a square wave.Ī quick word about pulse width: One way square waves can be manipulated is by adjusting the “Duty Cycle.” This means changing the ratio of how long the signal is high versus how long the signal is low. Repeating this process over and over would produce a square wave. Consider our example from last week, If instead of turning the power on and leaving it, you turned it on, waited for a period, then turned it back off. First stepping up to the high voltage mark, then after some time stepping back down. They are easy to understand and easy to create, but how do they relate to the step response?Ī square wave can be visualized as nothing more than a series of steps. ![]() We’ve used square waves quite a bit when working with simple oscillators. ![]()
