What is the width of the main lobe?
The main lobe of the shape of the PRN conforming to the P(Y) code has a width that is twice its chipping frequency, that is, 20.46MHz.
What is the width of the main lobe of a rectangular window?
(The mainlobe width of a rectangular window is 2/M, where M is the window length.) When we know that the original signal is a sum of two cosines, then each peak in the windowed signal's DTFT has the same width, because it is formed by convolving the window's mainlobe with the underlying impulse in frequency.
What is the main lobe width of Blackman window?
Explanation: The transition width of the main lobe in the case of Blackman window is equal to 12π/M where M is the length of the window.
What is the significance of the main lobe width of the window?
A practical engineering definition of main-lobe width is the minimum distance about the center such that the window-transform magnitude does not exceed the specified side-lobe level anywhere outside this interval. Such a definition always gives a smaller main-lobe width than does a definition based on zero crossings.
