  2. Nyquist stability criterion - Wikipedia

    en.wikipedia.org/wiki/Nyquist_stability_criterion

    The Nyquist plot for () = + + with s = jω.. 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 ...

  4. Hall circles - Wikipedia

    en.wikipedia.org/wiki/Hall_circles

    Nichols plot of the transfer function 1/s(1+s)(1+2s) along with the modified M and N circles. To use the Hall circles, a plot of M and N circles is done over the Nyquist plot of the open-loop transfer function. The points of the intersection between these graphics give the corresponding value of the closed-loop transfer function.

  6. MacGuffin - Wikipedia

    en.wikipedia.org/wiki/MacGuffin

    The use of a MacGuffin as a plot device predates the name MacGuffin. The Holy Grail of Arthurian legend has been cited as an early example of a MacGuffin. The Holy Grail is the desired object that is essential to initiate and advance the plot, but the final disposition of the Grail is never revealed, suggesting that the object is not of significance in itself.

  8. Undersampling - Wikipedia

    en.wikipedia.org/wiki/Undersampling

    Plot of sample rates (y axis) versus the upper edge frequency (x axis) for a band of width 1; grays areas are combinations that are "allowed" in the sense that no two frequencies in the band alias to same frequency. The darker gray areas correspond to undersampling with the maximum value of n in the equations of this section.

    The first act is usually used for exposition, to establish the main characters, their relationships, and the world they live in.Later in the first act, a dynamic, on-screen incident occurs, known as the inciting incident, or catalyst, that confronts the main character (the protagonist), and whose attempts to deal with this incident lead to a second and more dramatic situation, known as the ...
