Short-range-radio co-existence is now possible using CTCSS carrier generation with a 256-B sine-wave lookup table. To allow multiple users to share one carrier frequency, many handheld transceivers ...
producing the frequency predicted by equation (8). Higher-order harmonics can be calculated similarly. As an example, Figure 1 shows the output spectrum for the quad-channel, 16-bit, 2.5 Gsps DAC38J84 ...
