Definitions and Overview Flashcards
Define “Transducer”
Any device that converts one form of energy to another
Define “Signal Conditioning”
A collection of circuit functions that process a signal in order to change one or more of its properties
Define an “Active Circuit”
Requires a power input to change a property of a signal
Define “Amplification”
Increasing the power of a signal
Define “Attenuation”
Decreasing the power of a signal
Define “Impedance conversion”
A circuit that offers a voltage gain without a power gain.
What are some examples of impedance conversion?
> Buffering
> Impedance matching
Define “Filtering”
The separation of signals on the bases of their frequency content.
What is the diagram direction convention for a circuit diagram?
Left-to-right
What is the diagram direction convention for programming?
Top-to-bottom
What are the features of a circuit diagram?
> Contain the tropology of the component connections
> Drawn schematically (This means using simplified symbols for each component)
What are the features of a system diagram?
> Relationship between functional blocks within a system.
> Indicates the flow of inputs and outputs between each block
What are the features of a system concept diagram?
> Tells you how a system operates conceptually.
> Not concerned with circuit-level details Includes:
> Main functional blocks to understand the operating concept
> Relationship between each block
> Direction of interconnecting signals
What are the features of a system module diagram?
> Enables you to see how real subsystem parts are connected
> Not concerned with circuit-level details Includes:
> All modules required for practical implementation of the system
> Nature of the signals:
- Signal types/levels
- Distribution of power
