In VHF spectrum Analyzer, two types of frequency instabilities which will cause difficulties when narrow frequency range are displayed are known as (a) Short-term instability (b) Phase-noise (c) Correlation-noise (d) Long-term instability Choose the correct option
The Fourier transform of a signal x(t), denoted by X(jω), is shown in the figure. Let y(t) = x(t) + ejtx(t). The value of Fourier transforms of y(t) evaluated at the angular frequency ω = 0.5 rad/s is
A function f (t) is shown in the figure. The Fourier transform F(ω) of f(t) is
