Inductive components and capacitive components are both energy storage elements, with capacitors storing energy in the form of voltage (the energy stored in a capacitor at any moment is (1/2)CUc22), while inductive components store magnetic energy, represented in the form of current (the energy stored in an inductor at any moment is (1/2)LiL22). Since energy … Read more

This article demonstrates how to perform circuit simulation using MATLAB to measure the voltage of an RLC circuit. I am using R2014a, and the interface may vary slightly in different versions of the software. Open the MATLAB software and create a new Simulink Model, as shown in the figure below. After the untitled window pops … Read more
Minimum Shift Keying (MSK) is a special type of Continuous Phase Frequency Shift Keying (CPFSK) modulation method. It has advantages such as constant signal envelope, continuous phase, high bandwidth efficiency, and good power spectral characteristics, making it widely used in mobile communications, satellite communications, and other scenarios where signal quality and bandwidth resources are strictly … Read more
In the book “Passive/Active Phased Array Radar, Electronic Scanning Arrays, and Typical Systems,” there is an animated visualization that some have asked how to create. Today, we will analyze it and provide a step-by-step guide on how to create it yourself. Animation Analysis: We observe that this is a beam scanning diagram of a linear … Read more

Four-level Frequency Shift Keying (4FSK) is an important branch of digital modulation technology, representing four-level symbols (each symbol carries 2 bits of binary information) through four different frequency carrier signals. It is widely used in fields such as wireless communication and industrial control. Its core advantages lie in strong anti-interference capability and low implementation complexity, … Read more
In automotive MBD (Model-Based Design) development, the Delay Module in Simulink is an extremely fundamental yet crucial component. For example, by using the Delay Module, we can simulate physical world delays, including delays in sensors, actuators, and communications: Actual sensors (such as temperature, pressure, and position sensors) experience physical delays (mechanical response, filtering, signal processing … Read more
