The output of the Wavetek function generator can be modulated at 400 Hz by an inter-
nally generated sine wave. The modulation can be either AM (amplitude modulation)
or FM (frequency modulation). To enable this function push the button marked MOD
ON. The knob marked MOD/DEPTH-SWEEP RATE controls whether the modula-
tion is AM (knob in) or FM (knob out). The amount of modulation is controlled by
rotating this knob. An output or “ carrier” frequency of about 10 kHz is suggested. Ob-
serve the modulated signal on the scope. Can you measure the period of the amplitude
modulation of this wave?
