The term gain has a different meaning in antenna design; antenna gain is the ratio of radiation intensity from a directional antenna to / (mean radiation intensity from a lossless antenna). Graph of the input v i ( t ) {\displaystyle v_{i}(t)} (blue) and output voltage v o ( t ) {\displaystyle v_{o}(t)} (red) of an ideal linear amplifier with a ...
Nonetheless, the voltage gain is appreciable even for small loads: according to the table, with R S = r E the gain is A v = g m R L / 2. For larger source impedances, the gain is determined by the resistor ratio R L / R S, and not by the transistor properties, which can be an advantage where insensitivity to temperature or transistor variations ...
This is more commonly used than scalar linear gain and a positive quantity is normally understood as simply a "gain", while a negative quantity is a "negative gain" (a "loss"), equivalent to its magnitude in dB. For example, at 100 MHz, a 10 m length of cable may have a gain of −1 dB, equal to a loss of 1 dB.
These differences mean the vast majority of standard operational amplifier applications aren't directly implementable with OTAs. However, OTAs can implement voltage-controlled filters, voltage-controlled oscillators (e.g. variable frequency oscillators), voltage-controlled resistors, and voltage-controlled variable gain amplifiers.

The ground loop still exists, but the two sides of the loop are close together, so stray magnetic fields induce equal currents in both sides, which cancel out. Break in the shield Create a break in the signal cable shield conductor. [5] The break should be at the load end. This is often called ground lifting. It is the simplest solution; it ...
