We are giving a single value of bandwidth frequency, in the applied random signal. What does that bandwidth mean? It specifies zero to that frequency range or not.
Not from zero exactly but the minimum frequency that the signal generator can generate up to that number.
Dear Raja Velusamy The basic bandwidth of the signal is the range of frequencies: the difference between the highest-frequency signal component and the lowest-frequency signal component. However, the bandwidth of the filter, as low pass filter, is the frequency range between "0Hz" and cut-off frequency at -3dB attenuation (or sqrt (2) voltage amplitude reduction at cut-off frequency).
Dear Raja Velusamy , if your intention is to produce a random signal, the bandwidth range will be the frequency range where the signal is set to exist. As the signal type is random, it will have an approximate constant level (amplitude) inside all the bandwith range. Outside the specified range, signal level should go to zero. You also should be able to control the amplitude (gain) of your signal.
