Abstract:Diplomska naloga opisuje načrtovanje in izdelavo tiskanine za instrumentacijski ojačevalnik z zvočnikom in nastavljivim ojačanjem. Namenjen je zaznavanju zvokov različnih frekvenc na daljših razdaljah kot z mikrofonom. Opisal sem načrtovanje vezja skupaj s simulacijo v Multisim in Ultiboard. Sledi izdelava tiskanine instrumentacijskega ojačevalnika in meritve zvokov z ojačevalnikom in zvočniki. Rezultati meritev zvokov prikazujejo spremembo amplitud,e glede na čas pri spremembi frekvenc in ojačanja na instrumentacijskem ojačevalniku. Rezultate, ki sem jih dobil s simulacijo v LabVIEW programu, sem potrdil z meritvami enakih frekvenc z zvočniki. Zvoke sem izmeril na strojnih škarjah, rezalniku cevi in pralnem stroju.

Title:Instrumentation amplifier for the detection of distant acoustic signals using a loudspeaker
Abstract:Thesis describes the design and production of printed circuit board for an instrumentation amplifier with a speaker and adjustable gain. It is designed to detect sounds of different frequencies, at longer distances than with a microphone. I described the planning process of the circuit design along with a simulation in Multisim and Ultiboard. This is followed by the production of the printed circuit board of the instrumentation amplifier and sound measurements with the amplifier and speakers. The results of sound measurements show the change of amplitude with time in respect to the change of frequencies and gain on the instrumentation amplifier. The results obtained by the simulation in the LabVIEW program were confirmed by measuring the same frequencies with the speakers. I measured the sounds on machine shears, a pipe cutter and a washing machine.
