Description
Block Variable Resistor (CE) simulates a variable resistor, controlled by a scalar signal Engee. Minimum resistance value — this is a constant defined in the library RF independent of the control signal Engee. The unit has two electrical RF ports, as well as a directional input for the control signal. Engee.
The block icon Variable Resistor (CE) It is dynamic and displays the current state of the applied noise parameter. This table shows how the block icon changes depending on the parameter status. Simulate noise.

Parameters
Main group
# Simulate noise — thermal noise simulation
Details
Check this box to simulate thermal noise in a variable resistor. Then in the block Configuration (CE) also check the box Simulate noise. Both checkboxes are set By default.
This parameter defines a current noise source with a one-sided power density equal to A2/Hz, where
-
— Boltzmann constant;
-
— parameter value Temperature, K in the block Configuration (CE).
