Hace 3 días · Fundamental theoretical work in telecommunications technology was developed by Harry Nyquist and Ralph Hartley in the 1920s. Information theory, as enunciated by Claude Shannon in 1948, provided a firm theoretical underpinning to understand the trade-offs between signal-to-noise ratio, bandwidth, and error-free transmission in the ...
Hace 3 días · In 1928 the thermal noise in a resistor was first measured by John B. Johnson, for which Harry Nyquist provided the theoretical analysis; this is now termed Johnson noise. During the 1920s, the one-time pad cipher was invented by Gilbert Vernam and Joseph Mauborgne at the laboratories.
Hace 3 días · Nyquist--Shannon--Kotelnikov Theorem: If a function f(t) contains no frequencies higher than B hertz, it is completely determined by giving its ordinates at a series of points spaced 1/(2B) seconds apart.
Hace 2 días · El ruido térmico, o ruido de Johnson-Nyquist, surge del movimiento aleatorio de electrones en un conductor y está presente en todos los dispositivos electrónicos. Comprender y calcular el ruido térmico es crucial para diseñar y optimizar circuitos electrónicos, especialmente en aplicaciones de bajo ruido.
