It's a mild tradeoff between the magnitude response of the filter and minimizing the impact of envelope distortion by maintaining a linear phase in the passband. One could argue the same would be achived by a Bessel-Thomson type filter, but this is the extreme of linear phase response. (a gaussian filter to inf dB) which is not necessarily the best compromise when you need to space multiple channels in a given amount of bandwidth. The B-T would be perfect, if your signal were the only one...probably not the case for your application so a gaussian is chosen as a reasonable compromise to prevent inter-channel interference.

What is GFSK technique?
An FSK Modulator is much the same as a GFSK Modulator ,but GFSK uses a Gaussian filter as well. In a GFSK modulator everything is the same as a FSK modulator except that before the baseband pulses (-1, 1) go into the FSK modulator, it is passed through a gaussian filter to make the pulse smoother so to limit its spectral width.
What is gaussian filter in term of image processing?
the gaussian filter is also known as Gaussian smoothing and is the result of blurring an image by a Gaussian function.
What is Gaussian low pass filter?
Gaussian low pass filter is a image smoothing filter which is used to smooth up a digital image...........
How Gaussian filter is used in image processing?
Gaussian Blur blurs image but you can use it to soften mask edges and to create different effects like Glamour glow.
Can you apply a Photoshop filter to a mask?
Yes you can, for example people usually use Filter > Blur > Gaussian Blur filter to soften edges of the mask.
Compear fsk and psk?
fsk and psk
What is fsk in communication?
fsk is nothing but frequency shift keying which is used in low speed modems.....
How can I apply a Gaussian blur in Photoshop to enhance the visual appeal of my image?
To apply a Gaussian blur in Photoshop, go to the "Filter" menu, select "Blur," and then choose "Gaussian Blur." Adjust the radius to control the amount of blur. This can help soften harsh edges, create a sense of depth, and enhance the overall visual appeal of your image.
What is block diagram of frequency shift keying modulation?
Block digram of fsk is the representation of fsk modulation
What is FSK in telecommunication?
FSK stands for Frequency Shift Keying. It allows for voice and data to be digitized and transferred over analog lines. There is a maximum transfer rate of FSK data at 1.6 Mbps.
What do you mean by gaussian?
The Gaussian distribution is the same as the normal distribution. Sometimes, "Gaussian" is used as in "Gaussian noise" and "Gaussian process." See related links, Interesting that Gauss did not first derive this distribution. That honor goes to de Moivre in 1773.
How can I add haze in Photoshop?
To add haze in Photoshop, you can use the "Gaussian Blur" filter to create a soft, diffused effect. First, duplicate the layer you want to add haze to. Then, apply the Gaussian Blur filter to the duplicated layer, adjusting the radius to control the amount of haze. Finally, adjust the layer opacity to blend the haze effect with the original image.
