signal power

Let the relevant bandwidth (B) of a digital communication system be 1 MHz and $kT = -174 \text{ dBm/Hz}$, where k is Boltzmann's constant and 'T' is equivalent noise temperature of...

A real band-limited random process $$X( t )$$ has two -sided power spectral density $$${S_x}\left( f \right) = \left\{ {\matrix{ {{{10}^{ - 6}}\left( {3000 - \left| f \right|} \rig...

Consider an angle modutated signal $$x(t) = 6\,\,\cos \,[2\,\pi \, \times {10^6}t + 2\sin (8000\pi t)\,4\cos (8000\pi t)]$$ V. The average power of x(t) is

Consider an angle modulated signal x(t) = 6cos[2$$\mathrm\pi$$x10 6 t+2sin(8000$$\mathrm\pi$$t) + 4cos(8000$$\mathrm\pi$$t)] V. The average power of x(t) is.

The PSD and the power of a signal g(t) are, respectively, S g ($$\omega$$) and P g . The PSD and the power of the signal ag(t) are, respectively
