2. To the degree to which a demodulator reaches the performance of a perfect theoretical demodulator. 3. In relation to any “processing gain” that may be provided due to the modulation employed (see Chapter 2). 1. Almost all demodulators require an input signal-to-noise ratio of at least 6 to 10 dB to operate properly. They can usually be designed to perform to within a range of 1 to 3 dB worse than a perfect theoretical demodulator. Curves showing the theoretical performance for various modulation techniques using a perfect demodulator are given in Chapter 8.
11 is the on-off keyed spectrum produced by modulating a carrier with the data signal. 121, we see that the spectra are identical except that the 2ASK spectrum has a strong carrier component and 2PSK lacks a carrier, as it is suppressed. The main lobe of the spectrum, which is usually transmitted, has a bandwidth at the first nulls that is two times the data rate. *Assuming finite bandwidth, where the rise and fall times of the ones and zeros are small but still not negligible. 1 1 Baseband data signal on-off keying a carrier.
Their performance limits a receiver’s ability to recover information: To the extent that the demodulator requires a minimum input signal-tonoise ratio to perform properly and to produce a given minimum output signal-to-noise ratio. ) 2.
