This is consistent with channel spacings of 200 kHz and 10 kHz, respectively. Take a look at the digital receiver block diagram shown in Figure 3. Note the strong similarity to the analog receiver ...

Figure 1: Basic digital receiver block diagram The accumulator is clocked at the A/D converter's sample clock frequency so that the local oscillator output sample rate matches the A/D sample rate.

Figure 1 shows a notional block diagram of a radar receiver/exciter. Notice that the LRU contains frequency references, local oscillator generation, up/down frequency conversion, and digital-to ...

To understand how an SSB transceiver works we must first review the basic architectures of radio receivers ... is to consider everything at the block diagram level: filters, amplifiers ...
