EWB Useful Analysis
Determines the quiescent DC
operating point of a circuit.
Calculates the AC small-signal circuit
response over a range of input frequency.
Shows circuit behaviour as a function of time
Breaks complex periodic waveforms into their
sinusoidal components.
Calculates the noise contribution from each
resistor and semiconductor device at the
specified output node.
Simulate harmonic distortion and intermodulation
distortion products for analogue small-signal
circuits.

EWB Useful Analysis
Verifies the operation of a circuit by simulating
across a range of values for a component
parameter.
Verifies the operation of a circuit by simulating
it at different temperatures.
Determines the stability of electronic circuits.
Calculates the DC small-signal transfer function
between an input source and two output
voltage nodes or the output variable for current.
Helps to identify the components that most
affect a circuit’s DC bias point or AC gain.
Explores the component parameters which give
the worst possible circuit performance.
Computes circuit response to random variations
in component parameters.
