  2. Bode plot - Wikipedia

    en.wikipedia.org/wiki/Bode_plot

    Figure 1B: Low-pass filter (1st-order, one-pole) Bode magnitude plot (top) and Bode phase plot (bottom). The red data curve is approximated by the straight black line. In electrical engineering and control theory, a Bode plot (/ ˈ b oʊ d i / BOH-dee) is a graph of the frequency response of a system.

    The Pyramid of the Sun is the largest building in Teotihuacan, and one of the largest in Mesoamerica.It is believed to have been constructed about 200 CE. [4] Found along the Avenue of the Dead, in between the Pyramid of the Moon and the Ciudadela, and in the shadow of the mountain Cerro Gordo, the pyramid is part of a large complex in the heart of the city.

  6. Pole–zero plot - Wikipedia

    en.wikipedia.org/wiki/Pole–zero_plot

    A pole-zero plot shows the location in the complex plane of the poles and zeros of the transfer function of a dynamic system, such as a controller, compensator, sensor, equalizer, filter, or communications channel. By convention, the poles of the system are indicated in the plot by an X while the zeros are indicated by a circle or O.

In control theory and stability theory, the Nyquist stability criterion or Strecker–Nyquist stability criterion, independently discovered by the German electrical engineer Felix Strecker [] at Siemens in 1930 [1] [2] [3] and the Swedish-American electrical engineer Harry Nyquist at Bell Telephone Laboratories in 1932, [4] is a graphical technique ...

  9. Astronomical coordinate systems - Wikipedia

    en.wikipedia.org/wiki/Astronomical_coordinate...

    The poles are located at ±90° from the fundamental plane. The primary direction is the starting point of the longitudinal coordinates. The origin is the zero distance point, the "center of the celestial sphere", although the definition of celestial sphere is ambiguous about the definition of its center point.
