Write a generator function named count_seq that doesn't take any parameters and generates a sequence that starts like this: 2, 1

-BARSIC- [3]

Answer:

#required generator function

def count_seq():

#starting with number 2. using string instead of integers for easy manipulation

n='2'

#looping indefinitely

while True:

#yielding the integer value of current n

yield int(n)

#initializing an empty string

next_value=''

#looping until n is an empty string

while len(n)>0:

#extracting first digit (as char)

first=n[0]

#consecutive count of this digit

count=0

#looping as long as n is non empty and first digit of n is same as first

while len(n)>0 and n[0]==first:

#incrementing count

count+=1

#removing first digit from n

n=n[1:]

#now appending count and first digit to next_value

next_value+='{}{}'.format(count,first)

#replacing n with next_value

n=next_value

#testing, remove if you don't need this

if __name__ == '__main__':

#creating a generator from count_seq()

gen=count_seq()

#looping for 10 times, printing next value

for i in range(10):

print(next(gen))

What is the numerical ratio that is equivalent to 19.2 dB?

mrs_skeptik [129]

Answer: 83.17

Explanation:

By definition, the dB is an adimensional unit, used to simplify calculations when numbers are either too big or too small, specially in telecommunications.

It applies specifically to power, and it is defined as follows:

P (dB) = 10 log₁₀ P₁ / P₂

Usually P₂ is a reference, for instance, if P₂ = 1 mW, dB is called as dBm (dB referred to 1 mW), but it is always adimensional.

In our question, we know that we have a numerical ratio, that is expressed in dB as 19.2 dB.

Applying the dB definition, we can write the following:

10 log₁₀ X = 19.2 ⇒ log₁₀ X = 19.2 / 10 = 1.92

Solving the logarithmic equation, we can compute X as follows:

X = 10^1.92 = 83.17

X = 83.17
