ElectronicsModulating CarriersA2/A-levelOCR Created by: TavilineCreated on: 04-12-14 21:23 What are the disadvantages of using digital signals to transmit signals? Slow and limited data transfer 1 of 6 What is AM? When a high frequency carrier wave has a proportional amplitude voltage dependent on a signal. 2 of 6 What is the purpose of he MOSFET in the chopping circuit? A switch 3 of 6 What does a diode detector do in demodulation? Outputs a D.C. voltage that follows the signal peak value. 4 of 6 What does a multiplexer do in FM? Allows the ramp generator to produce a triangle wave. 5 of 6 How is frequency changed in FM? The signal voltage determines the ramp generator rate, which controls the schmitt trigger 6 of 6
