A PCM system consists of a PCM encoder (transmitter) and a PCM decoder (receiver). The essential operations in the PCM transmitter are sampling, quantizing and encoding. All the operations are usually performed in the same circuit called as analog-to digital convert Early electrical communications started to sample signals in order to multiplex samples from multiple telegraphy sources and to convey them over a single telegraph cable. The American inventor Moses G. Farmer conveyed telegraph time-division multiplexing (TDM) as early as 1853. Electrical engineer W. M. Miner, in 1903, used an electro-mechanical commutator for time-division multiplexing multiple telegraph signals; he also applied this technology to telephony.

elena-14-01-66 [18.8K]

Answer:

Replace your solution goes here with the following:

def compute_avg(num1, num2):

   func_name = "compute_avg()"

   print("FIXME: "+func_name)

   return -1

def get_user_num(user_num):

   func_name = "get_user_num()"

   print("FIXME: "+func_name)  

   return -1  

Explanation:

This defines the compute_avg function

def compute_avg(num1, num2):

This sets the function name

   func_name = "compute_avg()"

This prints the required output

   print("FIXME: "+func_name)

This returns -1

   return -1

This defines the get_user function

def get_user_num(user_num):

This sets the function name

   func_name = "get_user_num()"

This prints the required output

   print("FIXME: "+func_name)

This returns -1  

   return -1
