The ohms per volt figure is often called the "sensitivity" of the instrument. Thus a meter with a 50 μA movement will have a "sensitivity" of 20,000 Ω/V. "Per volt" refers to the fact that the impedance the meter presents to the circuit under test will be 20,000 Ω multiplied by the full-scale voltage to which the meter is set.
The following table is split into two groups based on whether it has a graphical visual interface or not. The latter requires a separate program to provide that feature, such as Qucs-S, [1] Oregano, [2] or a schematic design application that supports external simulators, such as KiCad or gEDA.
It offers the ability to set up a circuit with a graphical user interface and simulate the large-signal, small-signal and noise behaviour of the circuit. Originally, Qucs was composed of a circuit simulator "qucs-core", now Qucsator, and a GUI for schematic entry and plotting. The usage patterns, as well as the emphasis on RF design, were ...
Since ports are only attached to node 1 and node 4, nodes 2 and 3 need to be removed through Kron reduction. The table below shows the reduced Y parameter matrix of the Chebyshev filter example simulation after nodes 2 and 4 are eliminated. The nodes of the reduced table are renumbered to 1 and 2.
The actual output impedance for most devices is not the same as the rated output impedance. A power amplifier may have a rated impedance of 8 ohms, but the actual output impedance will vary depending on circuit conditions. The rated output impedance is the impedance into which the amplifier can deliver its maximum amount of power without failing.
In radio this device is also known as a dummy antenna or a radio frequency termination. It is a device, usually a resistor , used in place of an antenna to aid in testing a radio transmitter . It is substituted for the antenna while one adjusts the transmitter, so that no radio waves are radiated so that the transmitter does not interfere with ...
LTspice provides schematic capture to enter an electronic schematic for an electronic circuit, an enhanced SPICE type analog electronic circuit simulator, and a waveform viewer to show the results of the simulation. [2] Circuit simulation analysis based on transient, noise, AC, DC, DC transfer function, DC operating point can be performed and ...
NL5 performs transient simulation using modified nodal analysis and trapezoidal integration.A special algorithm is in place to handle simulation with ideal components (e.g. zero/infinite resistance and instantaneous switching).
