Disadvantages of Bandpass Sampling
Given Below are the Disadvantages of the Bandpass Sampling
- There maybe loss of data acquisition, as the sampling rate is not up to the range.
- In applying bandpass signal to relocate signals to the baseband position, the signal to noise ratio is not preserved leading to out of band noise being aliased.
- Due to aliasing, background noises in high frequency ranges are all folded into the low-frequency band causing mis-captured signal.
Bandpass Sampling in DSP
Real-world signals are measured as a function of time, distance, temp, etc., and processed to extract information from them. These signals are examined as analog and discrete signals for further operations. The digital signals x(n) are discrete and represented in zeros and ones.
Sampling is measuring the amplitude of the continuous signal at discrete regular intervals that define the number of values that are captured over a certain period of time to convert the signal from Analog to digital.
