Hi, I’m working on a logisim project for university.
I need to increase the clock frequency to 8/16 Hz, but the frequency must be set in the options to 1 Hz. How can I increase the frequency using only a circuit?
Thanks for the help.

What is the relationship (mathematical) between 1 Hz and 8/16 Hz?

I don’t understand the question sorry.
I need to double the clock frequency 3 or 4 times.

You phrased your question incorrectly. You said increase when you meant decrease.

Do you know how to divide a 1 Hz clock to 1/2 Hz?

Ah, thank you. I’m quiet new to circuits and I have lot to learn. I need my clock to be faster, so I though the frequency must be increased.

Read the above carefully. Frequency must be set to 1 Hz, but you need 0.5 Hz.

No, I need 8 or 16 Hz. The / means “or” not 8 divided by 16.

Not always. Why didn't you just use the word or to avoid confusion?

I don't see anything in Logisim that would enable you to do that.

It would need to support resistors (non-pullup variety) and capacitors.
