可编程斜坡发生器对音频有好处吗？

嗨，我正在寻找新的8位芯片，我看到有可编程斜坡发生器。你可以用一个可编程斜坡发生器吗？看起来像三角形的PWM，而不是脉冲。它对音频有好处吗？和PWM有什么区别？谢谢您

    Hi, i was looking to new 8 bit chips, i see there is programmable ramp generator.
What can you do with a programmable ramp generator ?,  looks like a PWM with triangle instead of pulses.
Is it good for audio ?, what is the difference with PWM ?

thank you
