LOWPASS: THIS PROGRAM DESIGNS ACTIVE LOW PASS FILTERS USING UNITY GAIN ACTIVE
ELEMENTS. THE INPUT IS THE 3 dB INPUT FREQUENCY, A SKIRT FREQUENCY AND THE
MAGNITUDE OF THE ATTENUATION IN dB AT THIS POINT. THE NUMBER OF SECTIONS IN
CASCADE IS CALCULATED. THE VALUES OF THE COMPONENTS IS CALCULATED. THE AUTHOR
REFERS TO TABLES GIVEN IN: EDN, MARCH 15,1971.
TUNEDAMP - Multiple-tuned Amplifier Program
The program was developed using a TRS-80 Model 4 computer with the DOSPLUS IV
operating system and Model 4 Basic, a version of Microsoft Basic which is
very similar to the one used on the IBM PC. The program should run with very
minor changes using any version of Microsoft Basic. The effects of any
statements which are peculiar to Model 4 Basic, DOSPLUS, or the Gemini 10
printer are explained by remarks in the program at those lines.
Abstract:
This program is used to design tuned amplifier coupling networks which
consist of one to eight tuned circuits each. These filter networks may be of
any conventional filter type, such as Butterworth, Chebyshev or Bessel. The
program calculates capacitor, inductor and resistor values, and transformer
turns ratios required to form a filter network with a specified shape, center
frequency, and bandwidth which will provide the desired mismatch ratios for
the transistors which are coupled by it.
The program also calculates low-pass prototype element values for
Butterworth and Chebyshev filters. For other types of filters these must be
from the keyboard.
