To receive free over-the-air digital broadcasts, your television, set-top box, or VCR must be equipped with a built-in digital tuner. If it does not have a built-in digital tuner, then you will need to connect a digital-to-analog converter box. Otherwise, you can subscribe to a ...
For a digital television system, the superhet portion is the same as it would be for an analog receiver, but the processing of signals after the demodulation block is very different. Figure 8.14 illustrates the IF response, which must be broad enough to include both sound and vision carriers...
