-To generate the AM signal use the math function from the Scopy signal generator. Set the main frequency ​to 100Hz and apply the following function: //​(1+0.5*cos(t))*3*cos(100*t)//​. The generated waveform is presented in Figure 3.+To generate the AM signal use the math function from the Scopy signal generator. Set the record length ​to 20ms, the sample rate to 75MSPS ​and apply the following function: //​(1+0.5*cos(2*pi*100*t))*3*cos(2*pi*100*100*t)//. The generated waveform is presented in Figure 3.
