Difference between Frequency Multiplier and Wave Cycle Multiplier 1

Share this:

Frequency multiplier and wave cycle multiplier are two completely different things.

Entering a Frequency Multiplier will only change the value of the frequency. Entering a Wave Cycle Multiplier has no effect on the frequency value. Instead, it alters how Spooky2 constructs the waveform, and thus allows the generator to output frequencies higher than its built-in hardware limit. It also allows Spooky2 to create complex waveforms like the damped sine/square and H-Bomb waveforms.

Perhaps an example can help you understand.

Example 1

Lets say you have the following set:
10, 16, 24

If you choose a Frequency Multiplier = 2, the software will send a command to the Spooky2-XM to generate the following frequencies:
20, 32, 48

However, if instead we set the Wave Cycle Multiplier = 2, the software will download a waveform with 2 periods in it, and send the commands to the Spooky2-XM generator to generate the following frequencies:
5, 8, 12

The software will show it generated 10, 16, 24, but the Spooky2-XM display will show 5, 8, 12. This is because the waveform contains 2 cycles.

Example 2

You can use the frequency set of 10, 16, 24 to generate the frequencies 10 MHz, 16 MHz, 24 Mhz (MHz = million hertz).

One might try setting the Frequency Multiplier = 1000000 (1 Mhz), to get the desired set. However, the Spooky2-XM internal clock can only go to 5000000 (5 Mhz), so the software sends a command to the Spooky2-XM to generate the following frequencies: 5000000, 4000000, 3000000.

These are the highest Octal sub harmonics of your desired frequencies under the 5 MHz limit of the XM.

However, if you use the Wave Cycle Multiplier to 10 in conjunction with the Frequency multiplier = 1000000 (1 MHz), the software will send a command to the Spooky2-XM to generate the following frequencies:
1000000, 1600000, 2400000.

The software will show it generated 10 MHz, 16 MHz, 24MHz, but the Spooky2-XM will show it generated 1 MHz, 1.6 MHz and 2.4 MHz.

  1. Thanks for helping me understand that each multiplier will be sending different frequencies depending on the setting you put on it. I guess I will just entrust this to a professional to make my old speakers work better. We just need to have a loudspeaker for the event I will have in my backyard to make the party really fun.
