iii Abstract Wide Frequency Range Superheterodyne Receiver Design and Simulation Chen-Yu Hsieh The receiver is the backbone of modern communication devices.
One problem of the problems of a superheterodyne receiver, is its ability to pick up a second or image frequency that is twice the intermediate frequency away from the signal frequency. For example, if we have a signal frequency of 1 MHz which is mixed with an IF of 455kHz.
A key decision in the design of a superheterodyne receiver is the choice of IF frequency. The IF frequency is related to the RF and LO frequencies by While it is possible to use a local oscillator either above or below the RF signal frequency,
gible, each sinusoid shows up at the receiver as a sinusoid of the same frequency, as we saw in Chapter 12. The reason is that an LTI system preserves the sinusoids.
The superheterodyne receiver has a built-in local oscillator that generates a weak signal at a frequency Fo that differs by a constant value from the frequency Fs of the received
One of the most common forms of radio receiver is the superhet or superheterodyne radio receiver. Virtually all broadcast radio receivers, as well as televisions, short wave receivers and commercial radios used the superheterodyne principle as the basis of their operation.
