Reading time: 2 minute The course presents several stands of mechanisms and a robot in which the reading of the kinematic parameters is done with incremental transducers of "MOUSE" type, and the data processing with educational programs, "C", "Pascal".
Reading time: <1 minut The thermistor is a resistor whose resistance is strongly dependent on temperature, as a result having a nonlinear UI characteristic. The decrease or increase of the resistance is in close correlation with the type of thermistor, which can be with the negative temperature coefficient, NTC or with the positive temperature coefficient, PTC.
Reading time: <1 minut A built-in system is a dynamic system, the system acting according to the received stimuli. When one or more system outputs must comply with certain rules, a controller manipulates the system input to bring the outputs to the desired values.
Reading time: <1 minut Embedded systems are computing systems built into electronic devices. The system implements a certain functionality. It is a combination of hardware and software designed to perform a specific function.
Reading time: <1 minut In general, sampling means the discretization over time of a continuous signal. In most practical applications, the sampling is uniform (it takes place at equidistant time moments), and the discrete time signals obtained by sampling are also quantified (discretized in value), being therefore numerical signals.
Reading time: <1 minut Data acquisition systems are complex systems for monitoring processes in which, as a rule, several physical quantities are involved. They perform the sampling of analog or digital signals (depending on the nature of the translator), in order to store, transmit or process the acquired information.
Reading time: 2 minute The conversion of information support at the level of a translator means the change of the nature of the size carrying information: the input size and the output size of the transducer are of different nature; if the output size is electric, the transducer is called electric.
Reading time: 2 minute In the field of electrical measurements, the sensor means a device that converts a certain physical or chemical quantity into an electrical quantity, the latter being able to be used to indicate the value of the measured quantity or even to control the system that generated it.
Reading time: <1 minut The reduction method consists in replacing the elements connected in series, parallel, parallel back, with their equivalent elements whose transfer functions are determined with the formulas specified above.
Reading time: <1 minut A rectifier is a circuit that converts bidirectional waves to monodirectional waves, or converts alternating current power to direct current power. For each simulated rectifier (of course) the transient analysis, the Fourier analysis and the transfer characteristic are generated.
