Introduction: This article discusses the potential interference from high-frequency electromagnetic waves in electronic signal processing circuits in practice. These situations are often omitted in ordinary classrooms and textbooks. The additional peripheral resistors and capacitors that seem unrelated to ordinary signal processing play a crucial role in ensuring circuit stability. Therefore, while encountering problems may cause … Read more

1. Limit Filtering Method 1. Method: Determine the maximum allowable deviation between two samples based on experience (set as A) When a new value is detected, judge: a. If the difference between this value and the last value <= A, then this value is valid b. If the difference between this value and the last … Read more
In vibration testing, vibration sensors serve as the most sensitive devices at the forefront of the testing system, and their stability and accuracy affect the results of the entire test. Therefore, how to select the appropriate sensor becomes very important. This article will introduce some selection tips for vibration accelerometers based on over 30 years … Read more
Problem Statement Dear Zhu, I recently encountered a problem that I would like to consult you about. We are using the OPA2350 for our electromagnetic operational amplifier, and instead of copying a board, I designed a circuit myself. The waveform simulated in Multisim is correct, and the rectified waveform is also correct; when I tested … Read more

Since we are starting from an example, we need to determine the overall scheme and relevant specifications. Based on this, we must design each module according to the workflow and determine the matching connection methods between them. This example begins processing from the intermediate frequency (IF) signal sampling. Following the mature scheme of the receiver, … Read more
