Hello anyone can solve it i need the codes on matlab.

Thank you in advance

3.1 Exercise 8. DPCM In this exercise, you will implement a simple DPCM encoding and decoding scheme as studied in Lecture 3 (slide 32). The encoder of the DPCM scheme quantizes the difference between the input signal (n) and a prediction i(n). It is possible to predict (n) in multiple ways. In this case, you will implement two different versions of the encoder: i. The first one (figure 2a) simply uses the reconstructed signal 3g(n) as the prediction for i(n) ii. The second one (figure 2b) does not make use of a prediction scheme. Instead, the error is simply computed as the difference between the sample z(n) with the input sample at the previous time step :(n-1). 011 PR Cader Decoder (a) DPCM encoder-dexoder scheme. 011 Cader (b) DPCM without prediction in the encoder. Figure 2 Exercise 8.1 Implement the two encoders mentioned above. For the DPCM encoder, you should follow the skeleton code provided in 'dpcm_encoder.m'. The code for the decoder is provided in 'dpcm_decoder.m'. 3.1 Exercise 8. DPCM In this exercise, you will implement a simple DPCM encoding and decoding scheme as studied in Lecture 3 (slide 32).
