On my visit to the National Media Museum in Bradford I came across a simple installation that explained the idea of 'bandwidth' in relation to television signals. In the case of television the term bandwidth refers to how much space is available to send information using a signal. Obviously early television pioneers had very little bandwidth, but as it developed more and more became available, for example today they have enough bandwidth to reproduce high definition images. The above two images show visually the difference between high and low bandwidth. The top image as high bandwidth and in turn is very sharp. While the bottom image has a very low bandwidth, resulting in a blurry image.
