An optical fibre has a reflective index of 1.641 for the core and 1.422 for the cladding. The critical angle above which the ray will be totally internally reflected is: Wavelength of the visible light extends from The type of by-pass capacitor that work best at high frequencies is Consider a binary transmission system with the symbol waveforms s 1 (t) = Acos(ω c t), s 2 (t) = -Acos(ω c t). This modulation format is termed as Given that F(s) is the one-sided Laplace transform of f(t), the Laplace transform of $$\int\limits_0^t {f\left( \tau \right)} d\tau $$ is
