In this video, two main topics will be covered: Pulse width modulation (PWM)
frequency and motor interfaces. In the first section, we will discuss what a
PWM frequency is, the definition of duty cycle and the effect it has on the
operation of a brushed DC motor. Additionally, we will discuss how to choose
an optimal switching frequency.
In the the second part of the video, we will discuss the different brushed
motor interfaces and their advantages/disadvantages in any particular system
as well as examples of logic tables.
