ltspice
my post lab question asks me to simulate a circuit using LTSpice. I am having trouble implementing it.
The circuit looks like this:
My issue is with the little diamond thing on the very right. I don't understand how it would be connected in LTSpice, because it looks like this:
Use the behavioral voltage source and apply the white() function there. Hit F2, then look for "bv" as the item in the dialog box. Drop that puppy down on the schematic. Do NOT use the regular voltage source for this.
Add a B source with a time value in the parameter"
For example put this in for the value of the B-source:
V=0.00205*sin(2 * pi * time * (1 + (2 * time)))
time is a system variable, so you are essentially doing this:
$$ V = A\sin(2\pi t*(1+\beta t))$$
The amplitude can be varied with A and the frequency with \$\beta\$, you can also choose other equations, there are if statements and other neat things you can do to generate a source.
You either have to do math or play with the values to get the starting frequency and ending frequency.

A dependent source is dependent on either a voltage or current. This lets us make feedback loops and other interesting circuits.
With a voltage controlled current source (VCCS) the control voltage comes from voltage source, the inputs to the source draws no current and the current from the source is based on this voltage. In this case the voltage is controlled from the differential voltage across the resistor. Like this:
