Exercise 6: Consider an audio signal with an amplitude that ranges over the interval [-10,10] and with spectral components limited to the frequency band of 300 Hz to 3300 Hz. The signal is sampled at a rate of 8000 samples/second and used to generate a PCM signal. The signal-to-quantization- noise ratio (SQNR) is required to be maintained at 43.9 dB a) What is the minimum number of uniform quantization levels needed, and what is the minimum number...

I'm having trouble writing this code, can some help me? Step 1: Capturing the input The first step is to write a functionGetInput()that inputs the expression from the keyboard and returns the tokens---the operands and operators---in a queue. You must write this function. To make the input easier to process, the operands and operators will be separated by one or more spaces, and the expression will be followed by #. For example, here’s a valid input to your program: 6...
