What is chirp bandwidth?
The chirp bandwidth can be straightforwardly computed as the product of βr times the duration of the pulse, i.e., the chirp rate can be expressed as. (5.74) where Br is the transmitted bandwidth and Tp is the duration of the pulse. A linear instantaneous frequency results in a quadratic phase, i.e., (5.75) π π
How does frequency chirping affect bandwidth?
As mentioned previously, frequency chirp has an effect of broadening the width of the signal optical spectrum and introducing system performance degradation when the transmission fiber is dispersive.
What is a chirp frequency?
What is frequency chirp? A chirp is a signal in which the frequency increases or decreases with time. This picture shows a linear chirp waveform; a sinusoidal wave that increases in frequency linearly over time.
What is a chirp in signal processing?
A chirp is a signal in which the frequency increases (up-chirp) or decreases (down-chirp) with time. In some sources, the term chirp is used interchangeably with sweep signal.
