Abstract
U nekim situacijama potrebno je izdvojiti signale određene frekvencije od ostalih, te je isto tako često potrebno izdvojiti pojedine harmoničke članove nesinusoidnog signala. U takve svrhe koristimo selektivne elektroničke voltmetre. Širina frekvencijskog pojasa selektivnog voltmetra iznosi od nekoliko Hz do nekoliko kHz. Budući da imaju malu širinu pojasa, imaju i malenu razinu šuma te stoga može pojačavati signale amplitude par μV. Frekvencijsko područje primjene selektivnog voltmetra je od nekoliko stotina kHz do više desetaka MHz, te se mogu upotrebljavati pri mjerenju faktora izobličenja, stupnja modulacije amplitudno-moduliranog signala i, pri mjerenju amplituda spektra signala. Selektivni elektronički voltmetar je u principu uskopojasno pojačalo koje izdvaja samo napon jedne frekvencije spektra, dok druge prigušuje

Parallel abstract (English)
In some situations, it is necessary to amplify or isolate signals with specific frequency, from another frequencies and it is also often necessary to isolate individual harmonics a non sinusoidal signals. For such purposes, selective electronic voltmeters are used. The bandwidth of such a voltmeter can be only a few Hz to a few kHz. Due to its very small bandwidth, such voltmeter has a small noise, and can amplify signals from a few μV. Frequency range of application of selective voltmeter, can span frequencies of several hundred kHz to several tens of Mhz, so they can be used to measure distortion factor, degree of modulation of amplitude-modulated signals and measuring the amplitude of the signal spectrum. Selective electronic voltmeter is generally narrow-band amplifier which distinguish voltage of one frequency spectrum, while others dim
