"WebThespectrogram is a tool that allows us to see the frequency properties of a signal as they change over time. The spectrogram works by taking multiple DFTs over small, overlapping segments1of a signal. The magnitudes of the resulting DFTs are then combined into a matrix and displayed as an image. Figure 7.1 shows the spectrogram of a DTMF signal. " - Inband image frequency

WebCo-channel interference or CCI is crosstalk from two different radio transmitters using the same channel. Co-channel interference can be caused by many factors from weather conditions to administrative and design issues. Co-channel interference may be controlled by various radio resource management schemes.

WebThe term f s i is called image frequency and is defined as the signal frequency plus twice the intermediate frequency .Reiterating , we have. f s i = f s + 2 f i. The rejection of an image frequency by a single –tuned circuit , i.e., the ratio of the gain at the signal frequency to the gain at the image frequency , is given by. α = 1 + Q 2 ρ 2. WebThe image rejection happens when the signal is actually in the desired band and its 'image' gets filtered. But if the signal itself comes in the negative frequency (ie the image band for the desired signal) the filtering would not help. In the image below you can see the chirp in green, the desired signal in blue and the interfere in red.

WebIn telecommunications, in-band signaling is the sending of control information within the same band or channel used for data such as voice or video. This is in contrast to out-of-band signaling which is sent over a different channel, or even over a separate network.
