Noun1.frequency-response curve- (electronics) a graph of frequency response with signal amplitude or gain plotted against frequency frequency-response characteristic electronics- the branch of physics that deals with the emission and effects of electrons and with the use of electronic devices ...
2. A plot of the gain or attenuation of a device, such as an amplifier or a filter, as a function of frequency. Note: A flat curve indicates a uniform gain or attenuation over the frequency range that the curve is flat. Most amplifiers will have a flat frequency response curve up to...
The significance of output impedance is ‘goodness of voltage source’. An amplifier with a very low output impedance will be able to maintain its output voltage without flinching, irrespective of load impedance dips. The output impedance is derived from the bandwidth plots, provided the amplifier...
Averaged frequency-following response to a 500-Hz tone burst, recorded between the vertex and linked ears with an amplifier filter bandpass of (A) 8 Hz to 10 000 Hz and (B) 200 Hz to 1000 Hz. The acoustic stimulus, recorded by a microphone at the subject's earpiece, is shown at the...
By utilizing the structure changing mode of the handset, the utility model can improve the sound quality, can generate an optimal sound effect, and can ensure that the frequency response curves of the telephone receiver in a sound amplifying mode and a sound receiving mode can both conform to ...
an RMS sensitivity of -8.92E+04 V/m3averaged over the frequency range 20-500 Hz. The same certificate also reports the frequency response curve of the instrument in dB scale. The reference to obtain the dB value is the sensitivity in the same spreadsheet -8.92E+04 V/m3. The frequency...
The experimental setup consists of a microsystem analyzer, which is a high-frequency laser Doppler vibrometer under which the microbeam is placed to measure the vibration, data acquisition card connected to an amplifier to provide actuation signals of wide range of frequencies and amplitudes, and ...
The limitation (first shown by Wheeler) of the gain-bandwidth product of an amplifier stage can be overcome, as earlier proposed by Percival, by connecting... HG Bassett,LC Kelly - Proceedings of the IEE - Part III: Radio and Communication Engineering 被引量: 11发表: 1954年 An Instrument ...
Of course, for practical applications, it's not necessary to measure (or specify) equipment at frequencies way beyond the frequency range of interest. For instance it's unnecessary to specify the response of an audio amplifier to radio frequency signals! However it's habitually the case that ...
The Battery Energy Storage System (BESS) has the advantages of large capacity, fast response, and bidirectional regulation; therefore, it has good prospects in power grid frequency control [4,5]. Energy storage-assisted thermal power unit frequency control is more suitable for the current power ...
