The electrical engineering section of the Radio Technologist provides practical solutions with theoretical backgrounds for electrical applications in wireless technology. One focus is the design and measurement of electric circuitry handling high frequent alternating currents.
Measuring Impedances with an Oscilloscope
The impedances of electrical components can be measured with high precision using an oscilloscope and a measuring transmitter. The method presented determines capacitances and inductances of unknown components as well as their frequency responses.
