In the measurements we deal with the basic circuits of electronics, such as the operational amplifier, the Schmitt trigger; we measure the effect of the Miller effect and the operation of the coincidence circuits. During the practice part the students solder electronic circuits themselves (e.g. astable multivibrator). They get introduced to the digital oscilloscope, to the lock-in method often used in experimental physics, and to a thermal circulation method suitable for measuring very low (water) flow rates.
