Join Barron Stone for an in-depth discussion in this video Protect against large signals, part of Electronics Foundations: Semiconductor Devices.
- Some electronic circuits are sensitive…and their components can be easily damaged…if they receive too large of an input signal,…much like how loud noises can hurt my sensitive ears.…If somebody is speaking to me at a reasonable volume -…- Hey Ben, how are ya?…- I'm doing fine Ray, thanks -…that's fine.…But if Ray's yelling in my ears,…- Who are you talking to?!…- that's too loud and can damage my ears,…so I need a way to protect myself…from those loud noises,…like earmuffs.…
- I still don't know who you're talking to!…- [Ben] When working with electronics,…a clipper circuit can be used to protect sensitive equipment…by limiting the amplitude of input signals.…The clipper will remove any parts of a signal…that are above or below a certain threshold voltage.…For example, the equipment I'm using right now…to record this video,…uses an amplifier to boost the audio signal…coming from my microphone,…and then it sends that amplified signal…to an analog-to-digital converter…connected to my computer.…
