How can I use a timer 555 IC to obtain a frequency multiplier? I made a frequency divider by using a timer in monostable mode but a multiplier looked difficult. Can somebody tell how can I design a multiplier?

Something like this could work for a multiple by two of a 50:50 square wave at a specific frequency.

The X-nor gate produces negative-going pulses on each edge of the input. The 555 produces an output pulse for each edge. Set the astable width appropriately.
