I want to input the frequency externally, it should give the triangular wave of that frequency

Hi, You could use the following setup in simulink

1. use wm as variable frequency input

2. set integrator in Wrap State mode with upper and lower value

3. use abs and level shifter to convert sawtooth into triangle waveform

Hope this could help.

Привет! Я сделал вот так. Но заметил, что если частоту менять слишком интенсивно, генератор начинает лагать. Например управляющая частота меняется от 100 до 500 kHz, а на выходе проскакивают мегагерцы. Ищу решение.
