1.	Why is pulse shaping technique used?(a) To increase ISI(b) To increase spectral width of modulated signal(c) To reduce ISI(d) To reduce power spectral densityThe question was asked in exam.I'd like to ask this question from Pulse Shaping Techniques in portion Modulation Techniques for Mobile Radio of Wireless/Mobile
Answer» The correct choice is (C) To reduce ISI Explanation: PULSE shaping techniques reduces the intersymbol interference. They are also used to reduce the spectral WIDTH of the modulated digital SIGNAL.
