Answer:
An analog signal is a continuous signal transmitted in the form of sine waves of varying <u>amplitude</u>
Explanation:
An analog signal is a step varying analog waveform that conveys information in a manner that is continuous in both amplitude and time
An analog process is one whose signal continuously varies, maintains a basic shape, and is transferable between mediums such that information is conveyed by analog signals based on analogy, which is one quantity tending to mimic another quantity's behavior
Signals of sound, voltage, data, voltage, or electric current can be transmitted as analog signals
A software that does and allows this is free software
Answer:
The function is as follows:
def concList(aList):
retList = ""
for i in aList:
if(str(i).isdigit()):
retList+=str(i)
else:
retList = "Not digits"
break;
return retList
Explanation:
This defines the function
def concList(aList):
This initializes the return string to an empty string
retList = ""
This iterates through aList
for i in aList:
This converts each element of the list to an empty list and checks if the string is digit
if(str(i).isdigit()):
If yes, the element is concatenated
retList+=str(i)
If otherwise
else:
The return string is set to "No digits"
retList = "Not digits"
And the loop is exited
break;
This returns the return string
return retList
