The probability density function F(x) = ae-b|x|, where x is a random variable whose allowable value range is from x = -∞ to x = +∞. The CDF for this function for x ≥ 0 is
A 4 GHz carrier is DSB-SC modulated by a low pass message signal with maximum frequency of 2 MHz. The resultant signal can be ideally sampled by sampling impulse train with frequency of
An angle modulated signal with carrier frequency ωc = 2π × 105 is described by the equation s(t) = 10cos(ωct + 5sin(3000πt) + 10sin(2000πt). What is the frequency deviation ∆f?
Determine whether the following statements are true or false with respect to Pulse Amplitude Modulation.
1. Instantaneous sampling of the message signal m(t) every Ts seconds, where the sampling rate $${{\text{f}}_{\text{s}}} = \frac{1}{{{{\text{T}}_{\text{s}}}}}$$ is chosen in accordance with the sampling theorem.
2. Lengthening the duration of each sample obtained to some constant value T
