Design a DTMF generator: Matlab or Python GUI design a function called “Key generator" GUI to create and record 8 tones according to the mobile phone standard that being used in Qatar o o o o The frequencies generated must be within +/- 1.5% of the assigned frequency. The high frequency in the tone must be 2 dB louder. The minimum tone duration is 40 ms. The minimum pause between tones is 40 ms. The sample frequency is 8KHz. You should add weight Gaussian noise to the recorded signals. You need to show the frequency domain representation of the signals and prove it satisfy the above constraints. o O O Write a Matlab or python function called “Key detector” to filter out the added noise, detect and determine the equivalent digit for each key and display it to the user. Develop a Matlab or python file called “main”
