Changes electrical energy to sound. component part of an electronic system device component Beath High School - Int 1 Physics 2 digital signals to inverter digital signals signals which are either on or off a system made up from electronic electronic system components input detects some type of energy and changes it into electrical energy intruder alarm an alarm which warns that someone has entered your house without permission inverter another name for a NOT gate Beath High School - Int 1 Physics 3 LDR to logic circuit LDR see light dependant resistor led see light emitting diode light dependant a special resistor which changes resistance as the light level changes resistor light emitting diode a voltage across it makes it light. Used to indicate when something is on or off. logic circuit a circuit which is made up of logic gates Beath High School - Int 1 Physics 4 logic gate to output logic gate used to combine or change digital electronic signals microphone changes sound energy into electrical energy NOT gate the simplest logic gate. It has one input and one output. The output is always the opposite of the input. OR gate the logic gate where the output is always at logic 1 unless both the inputs are at logic 0 when the output becomes logic 0 as well. output converts the electrical energy from the process subsystem into another type of energy which can be used. Beath High School - Int 1 Physics 5 process to system process public address system changes the electrical energy from the input so that the system can do its job. a system which allows announcements to be made to large number of people at one time sensor part of the input which detects changes around it sub-system small part of a larger system system something is made up of lots of parts which are put together to do a job, Beath High School - Int 1 Physics 6 thermistor to truth table thermistor a special resistor which changes resistance when the temperature changes truth table gives the outputs for the different combinations of the inputs of a logic gate Beath High School - Int 1 Physics 7 Intermediate 1 Physics Electronics End of Glossary Beath High School - Int 1 Physics 8
