Term
| What is threshold control? |
|
Definition
| The user set level that tells the processor when to work. If a signal doesn't pass the threshold, it won't activate. |

|
Term
|
Definition
|
|
Term
|
Definition
| It's what controls the strength of the processor once the signal passes the threshold. |
|
