The course aims to familiarize students with basic knowledge about 1. Methods of measurement signal and data acquisition using a dedicated hardware devices and computers category PC (importance of analog circuits and digital signal processing, dynamic measurements (measurement of periodic signals and one-time events, sampling frequency - Nyquist frequency, the frequency band of the measured signal - frequency filters, sampling the frequency lower than the Nyquist frequency). Autonomous measuring systems, distributed measurement systems, such as PC measuring and control unit - metering plug-in PC board (their structure and applications), galvanic isolation of the measured signal (with transformer isolation amplifiers, capacitive and optical coupling , converting DC signals using U / f and f / U converters), ensuring linearity of transfer methods for insulating amplifiers, multiplexers (for processing signals from multiple input) sampling circuit (sample / hold), instrumentation amplifier with programmable gain, D / A and A / D converters (converters use principles, methods, A / D conversion - converters with dual integration, successive approximation converter, parallel converter). Data storage during the measurement (data moving through the system interruptions, data storage into the temporary memory). 2. Operational amplifiers and their applications for analog signal processing (characteristics of an ideal operational amplifier possible sources of interfering signals in real OZ (voltage unbalance input bias current, input current unbalance, transfer characteristics - speed transfer), basic circuits with operational amplifiers (inverting amplifier, inverting amplifier, voltage follower, differential - instrumentation amplifier, differentiator amplifier, integrating amplifier, logarithmic amplifier), OZ protection against overloading input and output operational amplifier (exceeded limit parameter) compensation residual voltage input and quiescent current OZ, grounding and shielding involvement with OZ, the input resistance lines against interference bound capacitive and inductive coupling.)
