I want to detect all zero-crossings in a sine wave through matlab. Kindly tell me about a simple code which detects all zero-crossings and stores them in an array. The sine wave is continuous time signal, not discrete...
Zero-crossing detection is a method used to detect the moment when a signal crosses the zero axis. This is commonly used in signal processing and power systems to determine the frequency and amplitude of a signal.
Zero-crossing detection is important because it allows for accurate measurement and analysis of signals. It can also be used for triggering events, such as turning on or off a device at specific points in the signal.
Zero-crossing detection works by continuously monitoring a signal and detecting the point at which it crosses the zero axis. This is typically done by measuring the voltage or current level and comparing it to a reference value.
Zero-crossing detection has a wide range of applications, including power systems, audio and video processing, motor control, and telecommunications. It can also be used in data compression and encryption algorithms.
The main advantage of zero-crossing detection is its simplicity and low cost. It also provides accurate measurements and can be easily implemented in various electronic devices. Additionally, it can help reduce noise and improve the efficiency of power systems and signal processing.
