Why random signals are called power signals?
Energy signals are finite duration. That means if a random signal is energy type, all its realizations or its sample functions must be zero at infinity. So its expected value or mean is zero at infinity. On the other hand, a stationary process has a time invariant mean. So if its expected value is zero in infinity, it will be zero in any time. In summary if a stationary random signal is energy, its expected value must be zero every time. But It is not correct for all signals. So it is not energy type.
What is band limited signal?
A signal is said to be a band limited signal if all of it's frequency components are zero above a certain finite frequency. i.e it's power spectral density should be zero above the finite frequency.
Why do you use energy signal in real life although power of the energy signal is zero?
see p=E/t whr E is energy of a sig and t is time, if p iz zero it means t=0 and energy iz infinite means we can use max energy of a signal to travel it long distance,,,,,and it is possible only when power iz zero........
How can you generate blanking and raster ramp signal using fpga?
Blanking Means it's a Zero signal. But that zero signal is operate some V volts.
What is the amount of information in a continuous signal?
zero bits
