Question : Amplitude modulation is a process in which peak amplitude of the carrier signal varies in direct proportion to amplitude variations in the modulation signal (baseband). Student Answer: True False Points Received: 0 of 10
Comments: Question 6. Question : Frequency modulation is a process in which frequency of the carrier signal varies in direct proportion to frequency variations in the modulation signal Student Answer: True False ( proportion to amplitude) Points Received: 0 of 10 Comments: * Times are displayed in (GMT-07:00) Mountain Time (US & Canada) Grading Summary These are the automatically computed results of your exam.
