【實用工具app】FIL Calc|最夯免費app-綠色工廠好玩App

SUDOTECK released application FILCalc for iOS.This application has 3 calculation functions for RF Engeneer .Version 1.001) LPF calculator .2) HPF calculator .3) Air Coil calculator.Picker Wheel Data setting interface is very simple for all functions .DETAILS of functions1)LPF [Low Pass Filter]When you want to design LPF ,set the kind of filters using left wheel . [C1.] ... chebychev filter of ripple 1dB MAX . [C.5] ... chebychev filter of ripple 0.5dB MAX . [C.2] ... chebychev filter of ripple 0.2dB MAX . [But] ... Butterworth filter . [Bes] ... Bessel filter . And next whel select Number of components .Cut-off frequency is set with numeric 4 wheels and "KHz" , " MHz" wheel .An ideal characteristic is displayed on the screen. And calculated value will displayed ata each components .2)HPF [High Pass Filter]When you want to design LPF ,set the kind of filters using left wheel . And next whel select Number of components .Cut-off frequency is set with numeric 4 wheels and "KHz" , " MHz" wheel .An ideal characteristic is displayed on the screen. And calculated value will displayed ata each components .3)Air Coil calculatorTo developing filter circuits , you will often need to make some coils . The Air Coil is used for many filters .You can calculate the value of coil using [D]iameter wheel and [L]ength and [N] turn of coil .Info TAB will show you the responce of each kind of filters ,S11,S21 and groupe delay .Tap [i] button , you can jump File calc support WEB .
