This program is one of the family of "autonavigation programs". It is
intended to be a tool as a screw driver is. So you need not to read any
manual. The only thing you have to do is to number nodes in the schematic
diagram of the circuit being analyzed. The lowest number is 1, no number
must be missed nor doubled.
The circuit can obtain these elements:
R - resistor (a pair of nodes and value)
C - capacitor (a pair of nodes and value)
L - inductor (a pair of nodes and value of induction and Q)
M - mutual induction (value of the mutual induction and position of both
inductors)
V - transmission line (beginning, end, impedance etc.)
O - op. amplifier (two input nodes, output and reference nodes and two
supply voltages)
T - transistor (3 nodes and type - PNP, NPN, NMOS, PMOS)
I - current source controlled by voltage (a pair of nodes, nodes for control
voltage and value [ma/V])
( See files '*.SCH'. A T T E N T I O N - use command 'TYPE name.SCH';
do not try to print it !!!! )
Be careful. The most common mistake is open loops. That means the current
can't flow from one node to the next one until "going back".
If you chose 'Numeric', the program will compute admittance parametres, input
and output admittance and gain at defined frequency. If you choose 'U' or 'P'
you obtain a graph of the voltage or power depended upon the frequency. The
graph can be saved on disk as a file 'name.OBR'. You may this file print out
using program ZOBRAZ.EXE.
If you chose 'Change', you can change value of any element after typing its
number. After typing number 0 you will remove one element, if you type
number by 1 grater then the greatest item in the list of elements, you
will add one element. Anyway you can't add new t y p e of element.
The list of all used elements (incl. its values) can be obtain. That list
will be saved on the disk and its name will be 'name.FR#', where # is
automatically chosen number from 0 to 9. That file can be printed out.
You can also save input data. That file will be named 'name.FRE' and
c a n n n o t be printed! (It is a picture of computer's memory
only.). The actual list of files *.FRE is displayed and the arrows can be used
to moove to the next name.
Program ADMIT works very simillary. Input files 'name.FRE' can be read as by
FREZA as ADMIT.
