Noise Correction - Ameliorating Sensor Malfunction Sensors are key in the Internet of Things (IoT) devices and self-driving vehicles, and their use in a range of products is only expected to grow. Noise suppression is both important and essential for various types of sensors because serious accidents could occur if sensors do not correctly transmit the sensed data. Murata researched malfunction mechanisms and noise suppression methods, using one-chip type sensors (digital output type) as an example.
