IAEE DIoDES FD-151
Marry non-linear
phenornena nay be simulated
by using the conbina-
tion
of resistors
and diodes in the Free Fiodes trD-151 with the
potentioneters.
Applications
will
be shom: in Appendix 7.

TRANSIER DEL.A.Y ETEMEI\IT TD-151
The Transfer
Delay Elenent TD:151 causes tirre delay by Paders
second order appr"oxirnation.
Two dc arnplifiers
(a DA-151 or equiva-
lent)
are necessary for the cornplete circuit
as shor,rn in Figur.e
2.L0-1.
l^Iith two elenents corurected in series,
the transfer
delay girten
by Padet s fourbh
order approximation
can be approximately
produced,.
I:: this
connection,
the delay tirne will
develop to the sr:rn of the
value set i-n two elements.
Set a half
or nearly
a half
of delay tfune
on each element.
For better
simulation,
the fourüh order approxfina-
tion
rrril1 be recomnended.
The Transfer
Delay Elenent TD-151 has a wide range of delay time,
br.rt combination
of both R ald C which make the delay tiroe T rnrrst be
restricted
by the viewpoint
of sjmulating
aecuraey.
The Table 2.10-1
will
show a guide to select
a combi.nation of R and C.
The TD-151 can be used in both RealTi:ne Operation (nf) ana
Repetive 0peration
(RO), and the connection of capacitors
are auto-
natically
transfered
in a same way to, the Integrator,
synchronizing
to the Integrator
Capacitor switch on the Control Paner.
