  2. Impulse response - Wikipedia

    en.wikipedia.org/wiki/Impulse_response

    Control systems. In control theory the impulse response is the response of a system to a Dirac delta input. This proves useful in the analysis of dynamic systems; the Laplace transform of the delta function is 1, so the impulse response is equivalent to the inverse Laplace transform of the system's transfer function .

  3. Sound level meter - Wikipedia

    en.wikipedia.org/wiki/Sound_level_meter

    A sound level meter (also called sound pressure level meter ( SPL )) is used for acoustic measurements. It is commonly a hand-held instrument with a microphone. The best type of microphone for sound level meters is the condenser microphone, which combines precision with stability and reliability. [ 1] The diaphragm of the microphone responds to ...

  4. Time-domain reflectometer - Wikipedia

    en.wikipedia.org/wiki/Time-domain_reflectometer

    Time-domain reflectometer for cable fault detection. A time-domain reflectometer ( TDR) is an electronic instrument used to determine the characteristics of electrical lines by observing reflected pulses . It can be used to characterize and locate faults in metallic cables (for example, twisted pair wire or coaxial cable ), [ 1] and to locate ...

  5. Sawtooth wave - Wikipedia

    en.wikipedia.org/wiki/Sawtooth_wave

    The sawtooth wave (or saw wave) is a kind of non-sinusoidal waveform. It is so named based on its resemblance to the teeth of a plain-toothed saw with a zero rake angle. A single sawtooth, or an intermittently triggered sawtooth, is called a ramp waveform . The convention is that a sawtooth wave ramps upward and then sharply drops.

  6. High-frequency impulse-measurement - Wikipedia

    en.wikipedia.org/wiki/High-Frequency_Impulse...

    Physical basics. High-frequency-impulse measurement is an algorithm for obtaining frequency information of any structure- or air-borne sound source on the basis of discrete signal transformations. This is mostly done using [Fourier series] to quantify the distribution of the energy content of a sound signal in frequency space.

  7. Step response - Wikipedia

    en.wikipedia.org/wiki/Step_response

    The step response of a system in a given initial state consists of the time evolution of its outputs when its control inputs are Heaviside step functions. In electronic engineering and control theory, step response is the time behaviour of the outputs of a general system when its inputs change from zero to one in a very short time.

  8. Rise time - Wikipedia

    en.wikipedia.org/wiki/Rise_time

    Rise time is an analog parameter of fundamental importance in high speed electronics, since it is a measure of the ability of a circuit to respond to fast input signals. [8] There have been many efforts to reduce the rise times of circuits, generators, and data measuring and transmission equipment. These reductions tend to stem from research on ...

  9. Finite impulse response - Wikipedia

    en.wikipedia.org/wiki/Finite_impulse_response

    The result is a finite impulse response filter whose frequency response is modified from that of the IIR filter. Multiplying the infinite impulse by the window function in the time domain results in the frequency response of the IIR being convolved with the Fourier transform (or DTFT) of the window function. If the window's main lobe is narrow ...
