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 ...
Baker called the technique "back clamping", but the circuit is now called a Baker clamp. Many sources credit Baker's report for the two-diode clamp circuit. [ 3 ] [ 4 ] [ 5 ] Also in 1956, Baker described the circuit in a patent application; the 1961 issued patent US 3,010,031 [ 6 ] claims the use of the clamp in symmetrical flip-flop circuits.
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 electrode is attached to a wire that contacts the current/voltage loop inside the amplifier.
Columbia iron vane type clamp-on ammeter, with heads for different ranges. Less-expensive clamp meters use a rectifier circuit which actually reads mean current, but is calibrated to display the RMS current corresponding to the measured mean, giving a correct RMS reading only if the current is a sine wave.
Transient-voltage-suppression diodes are like silicon controlled rectifiers (SCRs) which trigger from overvoltage then clamp like Darlington transistors for lower voltage drop over a longer time period. In AC circuits a rectifier diode snubber cannot be used; if a simple RC snubber is not adequate a more complex bidirectional snubber design ...
This simple diode clamp will clamp the negative peaks of the incoming waveform to the common rail voltage. A diode clamp circuit can take a periodic alternating current signal that oscillates between positive and negative values, and vertically displace it such that either the positive or the negative peaks occur at a prescribed level. The ...
WASHINGTON – President Donald Trump faces a choice ahead of a Feb. 1 target date for his tariffs to begin kicking in: revenue or revenge? He campaigned on a blanket tariff that would generate ...
The actual clamping occurs in roughly one picosecond, but in a practical circuit the inductance of the wires leading to the device imposes a higher limit. This makes transient-voltage-suppression diodes useful for protection against very fast and often damaging voltage transients.
