M1 Exam Flashcards
In this filter, any signals having frequency in-between cutoff frequencies are rejected.
BAND-REJECT FILTER
This indicate the range of the stimulus in which the device is usable.
FREQUENCY RESPONSE
The movement of the sensor element is used to cause a change in electrical voltage, resistance, capacitance, or mutual inductance.
CONTACT SENSORS
Which among the choices is not one of the transducers selection factors?
Sensitivity
Cross Sensitivity
Reliability
Accuracy
Reliability
This represents the slope of the transfer function.
SENSITIVITY
This system is related to a network to access the resources.
NETWORK EMBEDDED SYSTEM
The experimental determination of the transfer function of actuator.
CALIBRATION
In this transducer selection factor, transducer shall maintain the expected input and output relationship as described by the transfer function to avoid errors.
ERRORS
This is the deviation of sensor’s output at any given point.
HYSTERESIS
This type of embedded system is categorized according to scale.
BASED ON PERFORMANCE OF THE MICROCONTROLLER(HINDI SURE)
or
Small-scale, medium-scale, sophisticated embedded systems
This converts the sensor output to suitable electrical form.
TRANSDUCTION ELEMENT
This converts the sensor output to suitable electrical form.
use points around the location of lowest curvature
use not equally spaced points
If the function is more complex need more slope
Calculate the slope and crossing point in V=aT+b
Calculate the slope and crossing point in V=aT+b
This is used to convert desired parameter into electrically measurable signal
SENSOR SYSTEMS
This is a functional computer system on a chip device that contains processor, memory, and programmable I/O devices.
MICROCONTROLLER
In this type of filter, any signal with a frequency lower than the cutoff frequency gets blocked.
HIGH PASS FILTER
This material is used for room temperature applications.
IMPREGNATED PAPER
In a passive filter, this has no gain. While in active filter, this may have gain depending on the configuration of the circuit.
PASSBAND
In this transducer selection factor, transducer shall not break down and maintain its input and output relationship under specified environmental condition.
ENVIRONMENTAL COMPATIBILITY
This is the extent to which the measured value might be wrong and normally expressed in percentage.
ACCURACY
This is related failure and success measurement and it is normally associated with calibration.
REPEATABILITY / REPRODUCIBILITY
In this transducer, the measurand is converted into a change in electrostatic charge or voltage generated by crystals when it is mechanically stressed.
PIEZO ELECTRIC INDUCTION
This is used to overcome the nonlinearity in the displacement sensor.
PUSH-PULL DISPLACEMENT SENSOR
This transducer converts the mechanical elongation and compression into resistance change.
STRAIN GAUGE
This is used as an additional processing unit for running the application in place of using embedded device.
APPLICATION SPECIFIC SYSTEM PROCESSOR (ASSP)
This type of strain gauge has wire stretched that can be made of nickel,
UNBONDED STRAIN GAUGE
This is the drop rate of gain of the filter.
ROLL-OFF RATE
This frequency is where the power of the output signal becomes half the power of the input signal.
CUTOFF FREQUENCY
These frequencies are defined by the cutoff frequency of the filter.
STOPBAND AND PASSBAND
This is usually taken to be less than -3dB of the input.
Gain/Stopband
Gain at the Stopband
Gain at the Stopband
In this transducer, measurand is converted to voltage induced in conductor by change in magnetic flux and in the absence of excitation.
ELECTROMAGNETIC TRANSDUCTION
These two materials are used as resistive materials for semiconductor gauges.
SILICON AND GERMANIUM

CAPACITIVE TRANSDUCTION
These are made of semiconductor material which have negative temperature coefficient of resistivity.
THERMISTOR
These transducer need external source of power for its operation.
PASSIVE TRANSDUCER
This system require scalable processor or configurable processor, and programming logic arrays.
SOPHISTICATED EMBEDDED SYSTEM
This is due to the inertia of the device in both mechanical and electrical factors.
RESPONSE TIME
This is capable of converting the physical quantity into a proportional quantity such as voltage or current.
