High-Frequency Characteristics

Plotting Frequency Characteristics of a Second-Order System with Different Damping Ratios Using MATLAB

by

First, write out the fractional expression of the second-order system, determine the frequency range to be plotted, and then use the bode function to plot the frequency characteristic curves of the system for different damping values. % Plotting frequency characteristics for different damping ratios wn1=10; zeta1=0.2:0.1:1.2; w1=logspace(-1,2,100); num1=wn1*wn1; figure(1); for k1=zeta1 den1=[1.0 2*k1*wn1 wn1*wn1 ]; … Read more

Considerations for MIPI Signal PCB Design

MIPI (Mobile Industry Processor Interface) is a core transmission standard for devices such as smartphones, tablets, and automotive systems, which includesD-PHY (used for CSI cameras/DSI displays) andC-PHY (higher bandwidth, no independent clock) physical layer protocols. Its characteristics include: Differential Signals: D-PHY includes 1 pair of clock + 1~4 pairs of data lines; C-PHY transmits embedded … Read more
