Almost every switched-mode power supply (SMPS) needs an EMI (Electro Magnetic Interference) input filter to suppress any disturbances of the SMPS on the power lines. This requirement having an input filter in the design ensures that no negative effect will occur in other parts of the systems connected to the power lines....

Vector Network Analyzers of Rohde&Schwarz family are able to measure magnitude and phase of complex S-parameters of a device under test (DUT) in the frequency domain. By means of the inverse Fourier transform the measurement results can be transformed to the time domain. Thus, the impulse or step response of the DUT...

For a computer system to recognize a memory module, the module needs to have a chip on it that communicates the specifications of the module to the system. A system’s basic input/output system (BIOS) may depend on serial presence detect (SPD) data to properly configure and optimize the memory sub system.
