English to German Tech/Engineering Electronics / Elect Eng matched pulse shaping filter

Kontext:

The bottom line of equation (1) describes the outer ***skirts*** 312 and 314 of the combined spectrum 310 from frequency-locations f2 = ((2-ß)/2T) to f3 = ((2+ß)/2T) and f5 = (-(2-ß)/2T) to f6 = (-(2+ß)/2T), respectively. The top line of equation (1) describes the constant portions 318 and 320 of the combined spectrum 310 from frequency locations fl = (ß/2T) to f2 = ((2-ß)/2T) and f4 = (-ß/2T) to f5 = (-(2-ß)/2T), respectively

Similarly to equation (1), above, the bottom line of equation (3) describes the ***skirts*** of the matched filter 214 characteristic S(f) and the top line of equation (3) describes the constant portion of the matched filter 214 characteristic S(f).

the pulse signal from the receiver front end is a near baseband signal having positive and negative frequency spectral images, each having a limited bandwidth and exhibiiing a ***skirt*** on the low frequency band edge; and
the carrier tracking loop translates the positive and negative frequency spectral images to baseband such that the ***skirts*** overlap near DC, producing
