Real and complex low pass equivalent of band-pass signal

1. What is low pass equivalent of bandpass signal?
2. What is the difference between low pass and bandpass signal?
3. What is baseband equivalent signal?
4. Is pass band and band pass are same?

What is low pass equivalent of bandpass signal?

phasor = equivalent lowpass signal representing the sinusoid (that's why we used the subscript l – for lowpass). Note that this equivalent lowpass signal is complex valued, whereas the bandpass signal (the sinusoid) it represents is real valued.

What is the difference between low pass and bandpass signal?

A bandpass filter allows signals between two specific frequencies to pass, but that discriminates against signals at certain frequencies. A lopass filter is a filter that passes signals with a frequency lower than a certain cutoff frequency and minimizes signals with frequencies higher than the cutoff.

What is baseband equivalent signal?

xE(t) is known as the equivalent baseband representation of the signal. It's really just the difference between the signal and the unmodulated carrier frequency, expressed in complex terms.

Is pass band and band pass are same?

The related term "bandpass" is an adjective that describes a type of filter or filtering process; it is frequently confused with "passband", which refers to the actual portion of affected spectrum.
