1.	Which of the following is used for demodulation of PAM signal?(a) a band reject filter(b) a band pass filter(c) a low pass filter(d) a high pass filterI had been asked this question by my school principal while I was bunking the class.Question is from Generation of VSB topic in chapter SSB Modulation of Analog Communications
Answer» Right choice is (c) a low pass filter The BEST I can explain: Pulse Amplitude MODULATION is the TRANSMISSION of data by varying the amplitude of different pulses. A low pass filter is always used to demodulate a PAM as it attenuates high FREQUENCIES and allows only low frequencies to pass.
