cd4013 and 74hc74

[jeep6789]

Does any of you know about the CD4013 or 74HC74 waveform shaping circuits? I want to use them to shape the square wave signal, but I'm not sure how to connect the wires. Thank you.

I can't recall which detector circuit contained the CD4013. Its usage suits me perfectly, but I've forgotten which circuit it was. Could everyone please help me? Thank you.

Here is an example for the cd4013.

A cd4046 could be used it has a flip flop on the vco output and built in timing oscillator

The Cscope 1220B has a waveform shaping circuit(VCO) using a 4013. By waveform shaping I take it to mean VCO?
