Hi For a full setup, you could do it a lot of ways. A setup of:
Antenna -> front end -> ADC -> MCU -> D/A would be one approach. Various bits like a local clock also would get into the design. There are *many* other approaches. ========== There are a lot of D/A’s that will clock in the 100’s of KHz range. If you are only trying to come up with an analog of a WWVB signal the “10 bit” D/A’s found in some MCU’s would do the trick. In the setup above, the ADC would likely be harder to come up with than the DAC. Since you are only trying to come up with a carrier, the need for a D/A is not an absolute one. Taking a square wave of some sort and filtering it a bit would be adequate to drive most of these old WWVB receivers.
