Schmitt trigger is used to generate PDM.(a) True(b) FalseThe question

1.	Schmitt trigger is used to generate PDM.(a) True(b) FalseThe question was asked in an interview for internship.This intriguing question originated from Frequency Discrimination Method topic in section SSB Modulation of Analog Communications
Answer» Right choice is (b) False Explanation: Pulse density MODULATION (PDM) is used to REPRESENT an ANALOG signal using a DIGITAL signal. For generating PDM, a monostable multi-vibrator is used, which is externally triggered and has only ONE stable state.
