TweetImportant Amplifier Properties Isolation For the biological subject, against electric shock from the amplifier’s power source(s)–or, how to not kill your patient while taking measurements! For the signal-to-noise ratio (SNR): isolation keeps the (60-Hz mains and other) noise out of the sensor pickup–and out of the amplifier input. One simple way to isolate the input [...]

TweetThis post is about amplifiers, how they work, and common applications. I will cover several operational amplifier configurations, and situations where each might be useful. This is part I of II for general discussion about amplifiers. Enjoy! Definition of an amplifier Definition (for Bioinstrumentation): Circuit that makes a small signal, usually voltage but occasionally current [...]
