How to generate PWM signal in MATLAB App Designer?

The provided content is about a video that demonstrates how to generate and plot a Pulse Width Modulation (PWM) signal in MATLAB App Designer’s UI Axes. The source code for the task is shared. It involves creating a class called PWMSignalApp with app components like UIAxes and PWMButton. After creating UIFigure and components, a function named PWMButtonPushed is declared. This function generates a sine wave and a PWM signal corresponding to it, plotting both signals on different UI Axes. The user is encouraged to direct any questions, suggestions, or appreciations to the provided contact email address.

How to design PWM signal with different ON and OFF period in Matlab Simulink?

The content reviews a video demonstration of how to use Simulink model design to generate a PWM (Pulse Width Modulation) signal with variable ON and OFF periods. The process involves using a CLOCK block to receive the time component, then applying a REM (remainder) block to acquire the remainder value from the timer. This value sets the threshold for the switch block, dictating the creation of the desired PWM signal. If viewers need additional help or have suggestions, they can contact the creators through their website or email.

How to set color brightness of an image using a SLIDER in MATLAB App R2023a?

The content provides a MATLAB App Designer R2023a developed application for image brightness control. The application modifies the brightness of an image using the dynamic slider value. The presented source code shows an ‘ImageControlApp’ class with properties that match with app components and callback methods which handle component events. The key function, ‘SliderValueChanging’, adjusts the image source according to the changing value of the slider for brightness control. The program further constructs and deletes the application along with the user interface figure, as needed. The application source code and video tutorial is available for better understanding.
