It's easy enough to find examples. 

For example RF [OOK](https://en.wikipedia.org/wiki/On%E2%80%93off_keying) modulation can be considered "digital" since it only has two states. Yet at the same time we can vary the carrier frequency, which can be considered "analog".

Another example is current loops where analog signals are transmitted as current. You can at the same time use this current to drive something with digital on/off characteristics, like a relay coil.
