Online ultrasonic monitoring of aqueous solutions involves acquisition of an ultrasonic waveform either propagated through the solution or reflected from a reflector placed inside it. Most conventional ultrasonic instruments upload the waveform to a separate computer which calculates from this waveform, e.g., the propagation delay and the attenuation(More)
Interleaved sampling is used by major DSO vendors for acquisition of periodic waveforms to increase the equivalent sampling frequency. These instruments use advanced proprietary solutions that are not applicable to low cost instrumentation easily. Accurate frame interleaved sampling becomes applicable when the waveform of interest can be excited at will,(More)
High accuracy data acquisition frequently employs averaging in order to improve the signal-to-noise ratio (SNR) of the output signal. Averaging requires acquisition of several copies of a noisy input signal that results in an increase in the measurement time, and is applicable for the periodic processes only. The SNR can alternatively be improved by digital(More)
This paper describes an approach for the development of an embedded web server that facilitates a remote access for a laboratory experiment for distance learning purposes. The experiment involves measurement of a voltampere characteristic of a semiconductor diode by setting the voltages applied to it remotely over the Internet. The learner observes two(More)
