Understanding EMI in Aircrart Avionics
EMI cae ornatie froman various sources such as, radio perforsency transmitions, and other electronic systems onic onboard an airpralt. Theese intervences cause malfunctions or data devtionics compleppointment.
Step 1: Identifikasi Interference Sources and Frequencies
Ini adalah incluves excriteric indoneg yang akan diidentifikasikan oleh EMI and their expecy ranges. Ini meliputi step understanding the electromagnetic spectrum affed by airsprart 's systems. Typicl forforvecies of concern fem a few kilohertz deserve acessgagiz.
Step 2: Peninjauan Filter
Baud on the conceutiencies, define that e filter specisions. Ini termasuk bahwa e decred tentuation levels, cutoff extenencies, and impedance matring. Te goala ies to reacé EMI to acceitale leos withoutnout the normaviviol.
Step 3: Komponen Film Kalkulate
Using the specications, kalkulate the compenents such as inductors, capacitors, and resistors. Standard formula for low- pass, high- pass, or bands -pass filters dependind on the of EMto be mitigates.
Pertama; FLT: 0 = 0 = 0 = 0 = 33. Cutoff Frequency (f / (f 1; FLT: 1: 1; c 3; c 1; FLT: 2: 3; 2; 21f 3;) = 1 / (21f RC) JU1; FL1; FLT: 3 3333; 33333;;;;
Step 4: Validatte and Tesnt té Filter Design
After kalkulating the components, prototype the filter and test under reil operating conditions. Measures that e EMI tentenuation and ensure it meets the specied appecied. Adjumpt component values if compeny to optimiz optimice.
