WHAT IS EMI & EMC IN PCB DESIGN

In this tutorial we are going to learn about WHAT IS EMI & EMC IN PCB DESIGN EMI: It is the process which gives out disruptive EM waves, transmits energy from one electronic device to another via radiated/conducted paths. In common usage, the term refers to RF signals. EMI Generally which have the frequency range […]

WHAT IS HIGH SPEED DIGITAL BOARD MATERIAL ?

In this tutorial we are going to learn about WHAT IS HIGH SPEED DIGITAL BOARD MATERIAL ? There are 2 basic types of circuits that fall under the heading of High Frequency-RF/analog (RF or micro- wave) & high-speed digital. Each of these has its own unique requirements, spawning 2 distinct classes of materials. Radio Frequency […]

WHAT IS THE FREQUENCY CHARACTERISTICS OF PASSIVE COMPONENTS ?

In this tutorial we are going to learn about WHAT IS THE FREQUENCY CHARACTERISTICS OF PASSIVE COMPONENTS ? Many designers are ignorant of the frequency limitations of the passive components they use in analog circuit. In Passive components have limited frequency ranges, and operation of the part outside of that range can have some unexpected […]

WHAT IS RESISTOR & ITS FORMULA

In this tutorial we are going to learn about WHAT IS RESISTOR & ITS FUNCTION RESISTOR: Resistance is property of resistor; It opposes the current by doing so it converts electric energy to heat energy                         R =ρl/a             l – Length                                                  a – Area ρ – Resistivity of material in ΩM Conductor –        Low […]
