2. Digital room correction - Wikipedia

   en.wikipedia.org/wiki/Digital_room_correction

   Digital room correction may involve minimum phase algorithms, to maintain wavefront coherence over the intended frequency range.. The use of analog filters, such as equalizers, to normalize the frequency response of a playback system has a long history; however, analog filters are very limited in their ability to correct the distortion found in many rooms.

3. Equalization (communications) - Wikipedia

   en.wikipedia.org/wiki/Equalization_(communications)

   A television equalizer consequently typically requires more filter sections than an audio equalizer. To keep this manageable, television equalizer sections were often combined into a single network using ladder topology to form a Cauer equalizer. The second issue is that phase equalization is essential for an analog television signal.

4. Zero-forcing equalizer - Wikipedia

   en.wikipedia.org/wiki/Zero-forcing_equalizer

   The zero-forcing equalizer applies the inverse of the channel frequency response to the received signal, to restore the signal after the channel. [1] It has many useful applications. For example, it is studied heavily for IEEE 802.11n (MIMO) where knowing the channel allows recovery of the two or more streams which will be received on top of ...

5. RIAA equalization - Wikipedia

   en.wikipedia.org/wiki/RIAA_equalization

   For example, the RIAA pre-emphasis in the popular Neumann SAB 74B equalizer applies a second-order roll off at 49.9 kHz, implemented by a Butterworth (maximally flat) active filter, plus an additional pole at 482 kHz. [2] This cannot be compensated for by a simple zero even if it were necessary, and in any case, other amplifiers will differ.

7. Gamma correction - Wikipedia

   en.wikipedia.org/wiki/Gamma_correction

   FRC is no true replacement for more bits. The 24-bit and 32-bit color depth formats have 8 bits per primary color. With Microsoft Windows 7 and above the user can set the gamma correction through the display color calibration tool dccw.exe or other programs. [26] [27] [28] These programs create an ICC profile file and load it

8. Fine adjustment screw - Wikipedia

   en.wikipedia.org/wiki/Fine_adjustment_screw

   A fine adjustment screw is a screw with threads between 40 and 100 threads per inch (TPI); 0.5–0.2 mm pitch. An ultra-fine adjustment screw has 100–508 TPI (0.2–0.05 mm pitch). Even though these are non-standard threads, both ISO metric screw thread designations and UNC designations have been used to call out thread dimensions and fit ...

9. Least-squares adjustment - Wikipedia

   en.wikipedia.org/wiki/Least-squares_adjustment

   Least-squares adjustment is a model for the solution of an overdetermined system of equations based on the principle of least squares of observation residuals. It is used extensively in the disciplines of surveying , geodesy , and photogrammetry —the field of geomatics , collectively.
