Circuit:
Both inputs are connected to a person's wrists (we tried it with fingers too).
The resistors are both 1Mohm
"What is the name of the resulting waveform?"
The Attempt at a Solution
All we saw is noise and something that looked like a triangle function (jagged zigzag type thing). I'm not sure we did this right and I was just wondering if this setup is called something specific that I could possible look up.
An operational amplifier (OpAmp) is an electronic circuit component that amplifies the voltage difference between its two input terminals. It is commonly used in electronic devices as a signal amplifier or in feedback control circuits.
An OpAmp typically consists of a differential amplifier with a large gain, followed by a feedback loop that controls the overall gain and output. The inputs are compared and the output is a voltage that is proportional to the difference between the inputs. This allows for precise amplification and manipulation of signals.
The inputs of an OpAmp are the inverting and non-inverting terminals, and the output is the amplified voltage. The inverting input is usually denoted by a negative sign (-) while the non-inverting input is denoted by a positive sign (+).
A waveform is a visual representation of a signal's amplitude over time. In an OpAmp with the same inputs, the waveform of the output will be identical to the waveform of the input, but with a larger amplitude. This is because the OpAmp amplifies the voltage difference between the inputs, resulting in a larger output signal.
OpAmps are used in a wide range of electronic devices and systems, including audio amplifiers, instrumentation amplifiers, active filters, and feedback control circuits. They are also commonly used in signal processing and communication systems.
