It is proved by written test that the student is able: – To list passive circuit elements R, L, C, linear/nonlinear, parametric/nonparametric, and to describe their properties. – To use the parametric elements for the construction of sensors of nonelectric quantities (temperature, mech. pressure, ...). – To list the basic laws and rules for solving of linear electric circuits, and to use it for solving of circuits. – To list and to define the basic transfer parameters of transfer two-ports. – To calculate and to draw the Bode diagrams (amplitude and phase) of the actual passive two-ports of RC and RLC types. – To calculate and to set the operation point of the bipolar transistor in any connection. – To list and to define the h-parameters of the bipolar transistor. – To calculate the voltage gain and input impedance of the bipolar transistor in various connections. To illustrate the connection and to explain the function of the differential amplifier, current mirror and constant current source. – To describe the inner structure of the simple operational amplifier and to explain the principle of its work. – To design the following linear circuits with operational amplifiers: P, I, D, PI. To calculate its transfer features in the frequency and time domain, to draw its Bode diagrams (ampl., phase). – To explain the difference between combinational and sequential digital circuits. – To list the axioms and lemmas of the Boolean algebra. To use it in the practical way to the minimization of logic expressions. – To create the logic expression from the logic table. In the laboratory practices the student measures and analyses signals in different electronic circuits using an oscilloscope. Each circuit (i.e. each work) is realized on a printed circuit board as in the real technical praxis. Student trains following skills: – To handle and to use basic measuring instruments in the electronics laboratory: oscilloscope, signal generator, laboratory supplies. – To measure properties of the phase pended loop with the circuit 4046. – To measure the transfer features of the operational amplifier in the invert and non-invert connections: P, P+LF filter of 1st order, follower. – To measure the transfer features of the active LF-filter of 2nd order with the operational amplifier. – To measure the static and dynamic features of the signal transistor in the switching regime. To design the optimal driving circuit of the transistor in the switching regime. – To measure and to analyze the static and dynamic features the operational amplifier connected as the comparator with/without the hysteresis. To realize the oscillator with help of the comparator with the hysteresis. – – To measure and to analyze the features the operational amplifier connected as the integrator. To use the integrator to the realization of the triangle signal generator. To create a PWM modulator using it. – To measure the static features of the constant current source with the bipolar transistor.
