SUDOTECK
released applicationFIL Calc for iOS.
This application has four calculation functions for RF Engeneer .
Version 1.00
1) LPF calculator .
2) HPF calculator .
3)Air Coilcalculator .
Picker Wheel Data setting interface is very simple for all functions .
DETAILS of functions
1) LPF
|
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
|
When you want to design HPF ,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
|
To 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 ..

4) Info
|
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 .
