1.	Who was the first to solve the problem of ISI?(a) Manchester(b) Faraday(c) Graham Bell(d) NyquistI got this question by my college director while I was bunking the class.This intriguing question comes from Pulse Shaping Techniques topic in division Modulation Techniques for Mobile Radio of Wireless/Mobile
Answer» The correct option is (d) Nyquist The explanation: Nyquist was the first to solve the problem of ISI. He OVERCOME the problem of ISI while keeping the transmission bandwidth low. He OBSERVED that ISI can be COMPLETELY nullified if at every instant, the response due to all symbols except the current symbol is EQUAL to zero.
