Pulse shaping filter for FSK

After a BPSK modulation we have the upsampling and the pulse shaping filter. But for a FSK, do we have upsampling and pulse shaping filter, or just the pulse shaping filter?

• In a modern implementation you would create the FSK signal in discrete time at a low intermediate frequency, then upconvert to RF in the analog front end. – MBaz Nov 8 '20 at 17:31

Most likely yes. FSK is already generated using many samples per symbol. Look at Matlab fskmod function.
