lynx.blocks.TransferFunctionBlock

class lynx.blocks.TransferFunctionBlock

Bases: Block

Transfer function block with numerator and denominator polynomials.

Parameters:

• num – Coefficients of numerator polynomial (highest degree first)

• den – Coefficients of denominator polynomial (highest degree first)

Example

H(s) = (s + 2) / (s^2 + 3s + 2) num = [1, 2] den = [1, 3, 2]

Ports:

Input: in (single input) Output: out (single output)

Methods

__init__(id, num, den[, position, label])	Initialize transfer function block.
add_parameter(name, value[, expression])	Add a parameter to the block.
add_port(port_id, port_type[, label])	Add a port to the block.
get_parameter(name)	Get parameter value by name.
get_ports()	Get all ports as dictionaries.
is_input_marker()	Check if this is an input marker block.
is_output_marker()	Check if this is an output marker block.
set_parameter(param_name, value)	Update block parameter and sync to parent diagram.
to_dict()	Serialize block to dictionary for JSON export.

__init__(id: str, num: List[float], den: List[float], position: Dict[str, float] | None = None, label: str | None = None) → None

Initialize transfer function block.

Parameters:

• id – Unique block identifier

• num – Numerator polynomial coefficients

• den – Denominator polynomial coefficients

• position – Optional {x, y} position on canvas

• label – Optional user-facing label (defaults to id)
