you can just do some"},{"startTime":171.5,"endTime":173.63,"body":"Googling, you can find some"},{"startTime":173.63,"endTime":176.81,"body":"tremendous stuff, but

a"},{"startTime":257.505,"endTime":259.274,"body":"little bit lost as we go over"},{"startTime":259.274,"endTime":261.985,"body":"these things here, but to"},{"startTime":259.274,"endTime":261.985,"body":"just bring you up to speed a"},{"startTime":261.985,"endTime":265.495,"body":"little bit, that episode was"},{"startTime":261.985,"endTime":265.495,"body":"all kind of like a very early"},{"startTime":265.495,"endTime":269.765,"body":"introduction to what impedance"},{"startTime":265.495,"endTime":269.765,"body":"control is, um, why engineers"},{"startTime":269.765,"endTime":272.474,"body":"need it, uh, a little

be."},{"startTime":282.34,"endTime":285.9,"body":"And that's where, uh, Ryan"},{"startTime":282.34,"endTime":285.9,"body":"comes in and we'll work with"},{"startTime":285.909,"endTime":288.4,"body":"customers to help them, uh,"},{"startTime":285.909,"endTime":288.4,"body":"understand how to do that."},{"startTime":288.4,"endTime":291.909,"body":"So episode 56, highly"},{"startTime":288.4,"endTime":291.909,"body":"recommend go back and listen"},{"startTime":291.909,"endTime":293.669,"body":"to that before getting"},{"startTime":291.909,"endTime":293.669,"body":"started with this episode."},{"startTime":294.069,"endTime":298.21,"body":"Um, and Ryan, so we, last"},{"startTime":294.069,"endTime":298.21,"body":"time we talked, you had,"},{"startTime":298.27,"endTime":301.389,"body":"you had thrown out, uh,"},{"startTime":298.27,"endTime":301.389,"body":"a few different types
