Goals and objectives
of the course in terms
of competences and skills
|1. To advance the knowledge about the close mutual dependence of signals in time base and in frequency base (spectrum). 2. To develop skills in choosing a suitable element of a circuit and its electrical regime for initiating desirable changes of the signal. 3. To develop skills in determining the reasons of existing changes of a signal in the circuit (basics of diagnostic). 4. To develop initial skills for creating variants of circuit for making suitable changes of the signal (basics of creative work).|
