AN2025 - Analog - Sine Wave Generation with PSoC® 1 (Demonstration with CTCSS)

Last Updated: 
Feb 19, 2018

AN2025 demonstrates how to generate a sine wave using two different methods: lookup table method and filtering method using PSoC® 1.

The document also shows how to implement a Continuous Tone Coded Squelch System (CTCSS) carrier generator in PSoC® 1. There are three projects associated with this document. The first two show how to generate sine wave using lookup table method and filtering method, and the third project demonstrates CTCSS implementation.
