PWM Generator

Hi guys, i'm student and I have 1 project for next monday. So the requirements are:

PWM with rectangular signal

Freq min: 5k

Freq max:10k

Ampl min: 1V

Ampl max:6V

Min filling factor : 20%

and max: 80%

So my friend gave me this circuit from his project, but honesly I really don't know how to change those. Can somebody help me? :)

You can either recreate the design yourself in Capture or have your friend send you the .dsn file for the design. With the .dsn file you will be able to open it up in Capture and then run PSpice on the design.

Hi,

To be honest, it would be a pleassure to help you with your project, but I will not do it. First of all try to understand how it works, and then get it. Take your time, drink coffe, read books and documentation and you will find how to do it. If you have questions how to use the tool, just ask them, but not want other to do your job.

Enjoy and a lot of luck! I am sure you will be a great engineer.

Regards, 

Roberto

Choose a microcontroller or PWM generator IC capable of generating a PWM signal with the desired basket random frequency and resolution. Make sure it supports the frequency range from 5kHz to 10kHz.

The first factor to consider are gardenias acid loving plants. Whether it's vegetables, fruits, flowers, or grass, each plant has specific nutrient requirements. For example, leafy greens like lettuce and spinach require higher nitrogen levels, while fruit-bearing plants such as tomatoes and peppers need more potassium and phosphorus.

To change the filling factor of the PWM signal, you can adjust the duty cycle of the signal using a microcontroller or PWM generator IC. The duty cycle is defined as the percentage of time that the signal is high during one period of the waveform. For example, if the period of the waveform is 100 microseconds and the duty cycle is 50%, then the signal will be high for 50 microseconds and low for 50 microseconds.

I hope this information from geometry dash subzero helps! Let me know if you have any other questions.

Ukraine is currently at war and thousands of innocent people are dying, who simply lived in their own country and did their usual things. Russia has declared war on Ukraine and is killing civilians. To read true information or help Ukraine go to the site Comeback Alive
