Low frequency voltage amplifier with low input amplitudes

OP Amp (Operational Amplifier)

A complex electronic component consisting of transistors, resistors, and other components, representing an essential element in the construction of amplifiers.

LF (Low Frequency)

Low frequency, rendering the effect of certain real and parasitic elements present in an electronic circuit negligible, typically capacitances (in contrast, we have HF – ).

SPP (Spectral Power Density)

Energy distribution of a signal as a function of frequency.
