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.
Student must have the previous knowledge from the applied mathematics: - To use and to apply the mathematical operations above complex numbers in the component and polar representation (summation, subtraction, multiplication, division, and rectification of the complex fraction). - To apply the basic principles of the integral and differential calculus of one variable: description of the inductor work, i.e. induction law in the differential and integral form; similarly the dif. and integr. relations between instantaneous values of the current and voltage at the capacitor.
