Radio Receiver Design - 166페이지
The percentage bandwidth* required of the local oscillator. When high-side injection is employed (the local oscillator frequency is higher than the input signal), the signal's upper and lower sidebands, if any, are inverted. For FSK signals, the ...

Communication Theory - 312페이지
It may be noted that the oscillator frequency can be greater or lesser than the carrier frequency. ... The mixer has two inputs: the amplified AM signal from the RF amplifier and a sinusoid from the local oscillator. The output of the mixer is an AM ...

Communication Engineering - 113페이지
When higher frequency stability of local oscillator is required, the circuits like AFC (Automatic Frequency Control) are used. Relation between oscillator frequency and signal frequency : We know that, for medium wave band, the signal ...

Consumer Electronics for Engineers - 12페이지
Because the difference signal is at a superaudio frequency, it is called a superheterodyne. A block diagram of a superheterodyne receiver is shown in Fig. 1.10. The local oscillator provides a more-or-less sinusoidal output that is mixed with ...

Monochrome and Colour Television - 138페이지
It may be noted that picture and sound signals would remain in the same relative position, i.e. , with sound carreir frequency higher than picture carrier frequency if local oscillator frequency is set below, instead of above the carriers. The local ...

Communication Systems,2E - 284페이지
It is not feasible practically to keep a constant difference between the local oscillator and incoming carrier frequencies for the entire band. The best that can be done is to adjust the difference exactly equal to IF at two points along the dial, ...
