Clamping circuits were common in analog television receivers. These sets have a DC restorer circuit, which returns the voltage of the video signal during the "back porch" of the line blanking (retrace) period to 0 V. Low-frequency interference, especially power line hum, induced onto the signal spoils the rendering of the image and, in extreme ...
Voltage and current errors: SEV-c circuitry does not actually measure the voltage of the cell being clamped (as does a two-electrode clamp). The patch-clamp amplifier is like a two-electrode clamp, except the voltage measuring and current passing circuits are connected (in the two-electrode clamp, they are connected through the cell). The ...
Sample times. Sample and hold. A sample-and-hold integrated circuit (Tesla MAC198) In electronics, a sample and hold (also known as sample and follow) circuit is an analog device that samples (captures, takes) the voltage of a continuously varying analog signal and holds (locks, freezes) its value at a constant level for a specified minimum ...
The saturation clamp supply needs to supply substantial current. [10] In contrast, the Baker clamp reduces the transistor base current rather than supplying more collector current. Another clamp circuit uses a single diode clamp. [9] It reduces base drive as the transistor nears saturation, but it uses a resistor divider network.
A digital clamp meter A multimeter with built-in clamp. Pushing the large button at the bottom opens the lower jaw of the clamp, allowing the clamp to be placed around a conductor. An electrical meter with integral AC current clamp is known as a clamp meter, clamp-on ammeter, tong tester, or colloquially as an amp clamp.
Simulation software allows for the modeling of circuit operation and is an invaluable analysis tool. Due to its highly accurate modeling capability, many colleges and universities use this type of software for the teaching of electronics technician and electronics engineering programs.

In order to characterize voltage-gated channels, the equations can be fitted to voltage clamp data. For a derivation of the Hodgkin–Huxley equations under voltage-clamp, see. [ 3 ] Briefly, when the membrane potential is held at a constant value (i.e., with a voltage clamp), for each value of the membrane potential the nonlinear gating ...
