First part (semester 4) deals with signal converting in circuits with lumped nonlinear elements. The main themes: Performance curves of elements. Approximation types of elements curves. Mutual dependence of signal spectrum and its time function. Some express methods of calculation of signal spectrum. The illustration of most popular conversions of signals: amplification (linear, resonant, broadband); signal frequency multiplications; transposition of spectrum of signals; modulation types of signals (amplitude, frequency, phase); demodulation of modulated signals; rectification and elimination of the amplitude of signals; design of different oscillators; frequency stability and synchronization; design of parametrical R and C elements; converting of signals by using parametrical elements; suggestions for low noise parametrical amplification. Second part (semester 5): Operational Amplifier fundamentals. Basic OpAmp Configurations, Instrumentation Amplifiers. Signal generators. Free running multivibrators. Triangular wave generators. Sawtooth wave generators. Function generators.
