Webb22 maj 2024 · Symmetry is a property that can make life quite easy when solving problems involving Fourier transforms. Basically what this property says is that since a rectangular function in time is a sinc function in frequency, then a sinc function in time will be a rectangular function in frequency. WebbRectangular Pulse Function. If a &lt; x &lt; b, then the rectangular pulse function equals 1. If x = a or x = b and a &lt;&gt; b, then the rectangular pulse function equals 1/2. Otherwise, it equals 0. The rectangular pulse function is also called the rectangle function, boxcar function, Pi function, or gate function.
