JAWAHARLAL NEHRU TECHNOLOGICAL UNIVERSITY HYDERABAD III Year B.Tech. ECE - II Sem L T/P/D C 0 -/3/2
DIGITAL SIGNAL PROCESSING LAB The programs shall be implemented in software (Using MATLAB / Lab view / C programming/ Equivalent) and hardware (Using TI / Analog devices / Motorola / Equivalent DSP processors). 1. Generation of Sinusoidal waveform / signal based on recursive difference equations 2. To find DFT / IDFT of given DT signal 3. To find frequency response of a given system given in (Transfer Function/ Differential equation form). 4. Implementation of FFT of given sequence 5. Determination of Power Spectrum of a given signal(s). 6. Implementation of LP FIR filter for a given sequence 7. Implementation of HP FIR filter for a given sequence 8. Implementation of LP IIR filter for a given sequence 9. Implementation of HP IIR filter for a given sequence 10. Generation of Sinusoidal signal through filtering 11. Generation of DTMF signals 12. Implementation of Decimation Process 13. Implementation of Interpolation Process 14. Implementation of I/D sampling rate converters 15. Audio application such as to plot a time and frequency display of microphone plus a cosine using DSP. Read a .wav file and match with their respective spectrograms. 16. Noise removal: Add noise above 3 KHz and then remove, interference suppression using 400 Hz tone. 17. Impulse response of first order and second order systems. Note: - Minimum of 12 experiments has to be conducted.
