The signal to noise ratio is one of the most commonly used ways of specifying the noise performance or sensitivity of a radio receiver. Noise generated within the receiver is what limits its sensitivity and not the amount of gain available. This means that measuring the signal to noise ratio for a signal of a given strength is a good way of determining the sensitivity. The signal to noise ratio, SNR method of specifying receiver sensitivity is most commonly used for HF radios, although it is equally applicable to other types of radio as well. Electronics Notes has launched a new video explaining what signal to noise ratio is and how it is used to specify the sensitivity performance of a radio. The video details a typical specification and explains each element of the specification. Watch the video:
Many thanks a very informative presentation. It’s a shame it wasn’t posted on the Front Page, this video deserved a bigger audience.
