E85.1801 Fundamentals of Music Technology Instructor: Juan P. Bello Assignment #8, Digital Systems This assignment is comprised of two sections: a problem set regarding sampling and an experiment involving MIDI. Problems: What is the lowest sampling rate on could use to represent the motion of the sun in the sky during the summer months in New York City. o Please explain your solution. Using a protractor/compass and graphing paper, draw a 5Hz sine wave (neatness counts). o Precisely sample this sine wave with a sampling rate of 9Hz. Below the 5Hz wave connect the resulting samples with sinusoidal curves. o What is the frequency of this new sine wave? o Repeat the sampling and redrawing process but this time sample the 5Hz wave with a sampling rate of 10Hz (again neatness and precision are very important). o Please discuss the resulting waveform. o Use a scanner to import your drawings into your report. Please be sure to
