What is the following image called in this course? - ANSWER Lamp of
Learning
Order the following computing elements from the earliest (old) to the more
recent (new) by its invention date. - ANSWER 1. Electron tube
2. Transistor
3. Integrated circuit
4. Large scale integrated circuit
"6004" is: - ANSWER The course at MIT that ELEN3431 is modelled after
Key elements of system engineering typically outlive the technologies they
interface to. - ANSWER True
Hierarchical design yields: - ANSWER Reusable building blocks and limited
complexity at each level
Assume that "27" is a Hexadecimal number. What is it in Binary? - ANSWER
00011011
PFET's are used in pull-up circuits while NEFT's are used in negating circuits. -
ANSWER False
Current flows between the diffusion terminals in a MOSFET if the voltage on
the gate terminal is such that it creates a conducting "channel", otherwise the
mosfet is off and current does not flow between the diffusion terminals. -
ANSWER True
What kind of FET is described by figure X? - ANSWER NFET
What does the VTC acronym mean? - ANSWER Voltage Transfer
Characteristic
, What must accept marginal inputs and provide unquestionable outputs? -
ANSWER Combinational device
What are sources of power supply noise? - ANSWER L(dl/dt) drop
IR drop
Can a combinational device contain directed cycles? - ANSWER False
Does a wire obey the static discipline? - ANSWER False
In general CMOS gate recipe, the output node is always a low-impedance node
in the steady state. - ANSWER True
If we design a system with lots of gain, what will that buy us? - ANSWER A
big noise margin.
TPD - ANSWER Time Propagation Delay (is the delay from valid inputs to
valid outputs)
TCD - ANSWER Time Contamination Delay (delay from invalid inputs to
invalid outputs)
What does the term ASCII mean? - ANSWER American Standard Code for
information interchange
If we use 2's complement for signed integers, we... - ANSWER an use addition
rules for subtracting
How is a Hexadecimal number identified? - ANSWER with a 0x prefix
How is a Octal number identified - ANSWER with a 0 prefix
Why can't we just keep compressing date over and over? - ANSWER When
the limit of redundancy has been reached for the encoding scheme, no more
compression can be achieved and the data volume may actually increase
