WebSCO is the sample clock mismatch observed at the receiver in parts-per-million (ppm), and E s and N o are the received symbol energy and noise energy, respectively. Figures 2, 3 and 4 show that for high E s/N o,SNR is adversely affected at the outer subcarrier locations by even small amounts of sample clock offset. Figure 3... WebBy interleaving these two 100 MSPS ADCs, the sample rate is increased to 200 MSPS. This extends each Nyquist zone from 50 MHz to 100 MHz, doubling the available bandwidth in which to operate. The increased operational bandwidth brings many advantages to applications across many market segments.
