Block Diagram Algebra Flashcards

Questions and Answers

What is a subsystem?

A subsystem is represented as a block with an input, an output and a transfer function.

What is cascade form?

Each signal is derived from the product of input times the transfer function.

Study Notes

Subsystems

A subsystem is depicted as a block with specified input, output, and transfer function.

Cascade Form

Signals are generated through the product of the input and the transfer function, allowing systematic signal flow.

Parallel Form

This configuration features a common input and output, derived from the algebraic sum of outputs from multiple subsystems.

Feedback Form

Represents a crucial feedback mechanism, characterized by the formula: input / (1 + input × Feedback).

Summing Junction

A symbol in block diagrams that illustrates the algebraic addition of two or more signal inputs.

Pickoff Point

Symbol in block diagrams indicating the distribution of a single signal to various subsystems, facilitating complex signal flow management.

Simplification Techniques

Involves forming an equivalent cascade in the forward path to streamline signal representation.
Requires the formation of an equivalent parallel system within the feedback path for efficient operation.
Includes the creation of a feedback system for enhanced control and stability.
