आयाम मॉड्यूलेशन (amplitude modulation) में, संदेश संकेत m(t) = 10 sin(2π × 105t) वोल्ट है और वाहक संकेत c(t) = 20 sin(2π × 107t) वोल्ट है। मॉड्यूलेटेड संकेत की बैंडविड्थ β kHz है। β का मान क्या है?

In amplitude modulation, if a message signal of 5 kHz is modulated by a carrier wave of frequency 900 kHz, then the frequencies of the sidebands are:

According to Nyquist's sampling theorem, a continuous band-limited signal with no frequency components higher than fm Hz can be uniquely reconstructed if it is sampled at uniform intervals spaced at most by:
