Frequency assignments are often made considering the problems with image frequency reception. Gah4 19:52, 30 April 2018 (UTC) Reply . I now removed: [dubious - discuss] As above, with a given RF stage filter, a higher LO frequency reduces image problems. That is, the image frequency will be more attenuated by a given filter.

In a heterodyne receiver (Fig. 7.2) the incoming (antenna) frequency is mixed to a usually lower intermediate frequency ( Fig. 7.3) where the entire RF signal processing and filtering is performed. This signal processing can be either analogue or digital. In the digital case the signal is digitized and fed into a signal processor, which.

Suppression of the image frequency is provided by a feedback loop connected between the output and an input of the adder circuit. In the feedback loop, the image frequency is cancelled by negative feedback and replaced by the complex conjugate of the desired frequencies. The complex conjugate is added coherently to the input signal at the adder.

Use a fairly high IF frequency,along with a bandpass filter at the input of the mixer,so that the "image frequency" is a long way out of the required tuning range of the receiver. The downside of this,is it is hard to get good selectivity with a high IF frequency in a simple Superhet.

There are two types of RF receiver modules: super heterodyne receivers and super-regenerative receivers. Super-regenerative modules are usually low cost and low power designs using a series of amplifiers to extract modulated data from a carrier wave. Super-regenerative modules are generally imprecise as their frequency of operation varies.

So in a typical receiver, picking up 95MHz would involve mixing it with a local oscillator at (95-10.7MHz) 84.3MHz. The two mixer output components would be the signal that was at 95MHz and the image at (84.3-10.7MHz) 73.6MHz. Hopefully they are far enough apart that the 73.6MHz would already have been eliminated by the front end filters.

Superheterodyne receivers, designed specifically for short-wave communication work, usually have a higher frequency for the I.F., from about 1,600 to 3,000 Kc/s, and may also incorporate double frequency changing. For example the receiver may change the incoming signal first to 3,000 Kc/s and then to 465 Kc/s or lower. [].

One major disadvantage to the superheterodyne receiver is the problem of image frequency. In heterodyne receivers, an image frequency is an undesired input frequency equal to the station frequency plus twice the intermediate frequency. The image frequency results in two stations being received at the same time, thus producing interference.

If the local oscillator frequency is moved up by 0.1 MHz to 5.1 MHz then the signal at 6.1 MHz will give rise to a signal at 1 MHz and this will pass through the IF. The signal at 6 MHz will give rise to a signal of 0.9 MHz at the IF and will be rejected. In this way the receiver acts as a variable frequency filter, and tuning is accomplished.

How does a heterodyne receiver work? The "heterodyne" or "beat" receiver has a local oscillator that produces a radio signal adjusted to be close in frequency to the incoming signal being received. When the two signals are mixed, a "beat" frequency equal to the difference between the two frequencies is created..

A super-het receiver first down-converts the received RF using an analog mixer. This is achieved by a suitable separate circuit labelled a "LOgen board" in Figure 3.
