Digital Electronics Objectives Part 14

261 . X ̶ X3/3!+X5/5! ̶ X7+… does the following subroutine computer

T = ̶ TXX*2/(Z(Z ̶ 1.0))
S1 = S

262 . The subroutine of the previous question will terminate when T <<S.

263 . FORTRAN variables may not be declared as TRIPLE PRECISION.

264 . 2 is the value of the FORTRAN integer variable M=2+62/33.

265 . Number 6 is printed by the FORTRAN code segment DO 1, I 3,7,3


2 . FORMAT(.1 X, 1 3)

266 . 49152 bytes does a 48K computer memory contain.

267 . the circuit given below is R-S latch.

268 . in register index addressing mode the effective address is given by the sum of the index register value and the operand.

269 . The circuit shown in fig.44 is a full subtractor.

270 . The I2L (integrated injection logic) has higher density of integration than TTL because it uses compact bipolar transistors.

271 . The most satisfactory LED driver circuit using a TTL gate is

272 . The refreshing rate of dynamic RAMs is in the range of 2 micro-seconds.

273 . A Schmitt trigger is a digital circuit that produces a rectangular output regardless of the input waveform.

274 . In a positive edge triggered JK flip-flop , a low J and a low K produce the inactive state. A high J and a high K mean that the output will toggle on the rising edge of the clock.

275 . The EPROM is ultraviolet light erasable and electrically programmable.

276 . CMOS is used extensively where lowest power consumption is necessary.

277 . The instruction just being processed is stored in the CPU is correct statement.

278 . The circuit shown in fig.46 is that of a TTL inverter.

279 . 2’s complement of -24 in a 16-bit microcomputer is 1111 1111 1110 1000.

280 . With a JK master slave flop-flop the master is clocked when the clock is high.
