Dive into the relationship between input and output impedance when connecting circuit elements. Learn when to make the source and load impedances equal or different to maximize the power or voltage that is transferred between components.
- [Narrator] When I string together multiple circuit…elements such as a microphone going through a filter,…an amplifier, and then finally a speaker,…some of those elements like the microphone function…as a source, which produces a signal as output.…Other circuit elements like the speaker will act…as a load which takes a signal as input,…and some of those circuit elements, like the amplifier…and filter, will act as both a source and a load,…taking a signal as an input, doing something to it,…and then providing the modified signal as output.…
When I connect these components,…I need to pay attention to how each of the sections…interfaced with each other in terms…of their input and output impedance.…For components that act as a signal source,…I'll need to pay attention to their output impedance,…which is also called the source impedance.…All electronic devices that produce signals…will have some amount of internal impedance at their output…terminals that opposes the AC signal passing through it.…Although the internal workings of the circuit…
