pathsim.blocks.amplifier module

class pathsim.blocks.amplifier.Amplifier(gain=1.0)

Bases: Block

Amplifies the input signal by multiplication with a constant gain term like this:

\[y(t) = \mathrm{gain} \cdot u(t)\]

Example

The block is initialized like this:

#amplification by factor 5
A = Amplifier(gain=5)

Parameters:

gain (float) – amplifier gain

op_alg

internal algebraic operator

Type:

Operator

update(t)

update system equation in fixed point loop

Note

SISO block has optimized ‘update’ method

Parameters:

t (float) – evaluation time

Returns:

error – deviation to previous iteration for convergence control

Return type:

float
