This is a fourth-order Butterworth low-pass filter with a cutoff frequency of 500 Hz and a passband gain of 10 (20 dB) this circuit was taken from. Digital components are treated as large resistances to ground.Ĭonsider the circuit shown in Figure 1.

AC circuit response is calculated as a function of frequency.Īssumptions: The analysis is applied to an analog circuit, small-signal.

If the Function Generator is set to a square or triangular waveform, it will automatically switch internally to a sinusoidal waveform.

All input sources are considered to be sinusoidal, their frequency is ignored.

Nonlinear components are represented by linear AC small-signal models, derived from the DC operating point solution.

AC sources, capacitors, and inductors are represented by their AC models.

Multisim constructs this matrix using the following approach:

A complex matrix, containing both real and imaginary components is created.

DC operating Point Analysis is performed to obtain the small-signal models.

Multisim performs AC Analysis using the following process: The result of an AC Analysis is displayed in two parts: gain versus frequency and phase versus frequency. Then, the equivalent circuit is analyzed from a start to a stop frequency. In AC Analysis, the DC operating point is first calculated to obtain linear, small-signal models for all nonlinear components. AC Analysis is used to calculate the small-signal response of a circuit.

* extended-precision numerical core (simulates circuits that make SPICE variants choke). * algebraically-defined behavioral sources (the ability to define voltage/current relations as an expression, like a spreadsheet or programming language) However, after you understand the concepts and the invariants, it would be rather unhelpful (or even distracting) to have an animated drawing of the tree as the algorithm progresses every time you were working with a BST!ĭisclosure - I wrote CircuitLab - another browser-based circuit simulator and schematic capture tool which doesn't do animated graphs, but instead includes: IMHO animated interactive visualization of the current flow is pretty to look at, but beyond a certain early point in one's understanding of voltage & current relationships, it's not necessarily more useful than not being there at all (and having non-interactive access only).įor a CS analogy: when you're trying to teach how and why to balance a binary search tree, it's useful to visually draw out the trees of the first few example steps. It's great to see all the new approaches in this field.
