Filters are electronic circuits, components or devices that perform signal processing functions, and are designed to remove unwanted components or enhance desired components from a signal.
A filter is a filter circuit composed of capacitors, inductors and resistors. The filter can effectively filter the frequency point of a specific frequency in the power line or the frequency other than the frequency point to obtain a power signal of a specific frequency, or eliminate the power signal of a specific frequency.
A filter is a frequency-selective device that allows certain frequency components in a signal to pass while greatly attenuating other frequency components. Using this frequency selection function of the filter, interference noise can be filtered out or spectrum analysis can be performed.
The filter generally has two ports, an input signal and an output signal. Using this feature, a square wave group or complex noise passing through the filter can be gated to obtain a sine wave of a specific frequency.
Filters are mainly used in signal processing, communication systems, audio equipment, radar systems, medical equipment, industrial automation and other fields
Quality is a company's consistent commitment to excellence in its operations. We have established a strict and standardized quality inspection process. Suppliers, quality inspection teams, and after-sales quality return visits are all important parts of the process.
Establish quality requirements for purchased products, regularly check suppliers to see if they continue to meet quality standards, and conduct evaluation audits on potential suppliers to ensure that they must meet the necessary quality standards.
The quality inspection team first conducts pre-purchase audits or inspections to ensure that the products sold to customers meet the standards. Inspect products for potential defects or non-conforming parts and record inspection results. Substandard products are rejected and suppliers are re-evaluated for continued cooperation.
Based on customer feedback to measure overall customer satisfaction with a product or reset, develop an action plan based on customer feedback to address problem areas.
Quality inspection of internal products and processes:
1. Develop a quality control plan that includes provisions for checking products and processes.
2. Establish procedures to investigate non-conformities and perform root cause analysis.
3. Develop a corrective action system to follow up non-conformities and corrective actions.
Customer quality inspection:
1. Establish a system to track customer feedback and change requests.
2. Establish a process for listening to customer feedback and taking appropriate action.
