## Description
The Signal Generator is similar to the Timer component, but its value isn't simply a counter. Instead, you can choose from a variety of familiar 'signals'. You configure the frequency by setting the Periodproperty, which is in milliseconds. You configure the resolution by setting the Values/Period property. 

For example, if you choose a sine wave signal with a period of 2000 milliseconds and 10 values/period, your sine wave will have a frequency of 0.5 Hz, and its value will change 10 times every 2 seconds.
