Maximizing sub-harmonics

[Ken Insworth]

I need to produce a signal, at any frequency below the regulated
boadcast band, that will be a sub-harmonic of a specific frequency in
the 10-15MHz range.

To maximize the effect, I assume a square wave with as high a rise
time as possible is advised, and at the highest practical frequency.

Are there any tricks of the trade on how to achieve the best possible
result with minimal cost and complexity.

Regards,

Ken

Since you've squared-up the signal, just use a digital divider.

** So you mean below AM band at 560 kHz - right ??

that will be a sub-harmonic of a specific frequency in
the 10-15MHz range.

** Means what exactly?

To maximize the effect,

** Which "'effect" is that ?

I assume a square wave with as high a rise
time as possible is advised, and at the highest practical frequency.

** Huh ???

Do you want "sub harmonics" or harmonics ??

Are there any tricks of the trade on how to achieve the best possible
result with minimal cost and complexity.

** What "result" is that ?

So far - your query is well in line for a vagueness award.
