1. The problem statement, all variables and given/known data analyze the MC1496 circuit and explain how it produces an AM signal. 2. Relevant equations 3. The attempt at a solution this is my understanding to modulation: Amplitude Modulation AM is mostly used when we need to transmit information over a radio signal; to do so we use a signal as a carrier to encode the information to be sent. The carrier in itself is just a sine wave of a given frequency and contains no information. For example radio stations are differed by using different carrier frequency to broadcast. To convey the information we have to modulate the carrier with the signal we want to broadcast. This is called Amplitude Modulation AM. The carrier frequency is kept fixed while we vary the amplitude of the since wave to encode the amplitude of the signal to be broadcasted. Amplitude modulation produces a signal with power concentrated at the carrier frequency and in two adjacent sidebands. The carrier frequency is in general much larger than the signal to be modulated. Modulation is a non linear process. In general we use a mixer to add the two signals. The mixer cannot be made of reistors or any linear devices otherwise it will be an adder not a mixer. With a linear circuit we won’t get the sum and difference frequencies out of it. however i am not able to analyze that particular circuit attached to this post and how it does the modulation. ANy help will be greatly appreciated.
