Lab 1: Sampling Theory‚ Quantization and PCM In this lab‚ you will familiar with Sampling theorem‚ quantization and PCM generation. Pre-lab Assignment : Given signal x(t) = sinc(t)‚ x(t). 1. Find out the Fourier transform of x(t)‚ X(f )‚ sketch them; 2. Find out the Nyquist sampling frequency of 3. Given sampling rate terms of fs ‚ write down the expression of the Fourier transform of xs (t) → Xs (f ) in fs = 1 Hz‚ sketch the sampled signal X(f ). xs (t) = x(kTs ) and the

DETERMINATION OF ABCESSION SIZE USING DIGITAL IMAGE PROCESSING TO AIDE ENDODONTIC THERAPY Karthikeyan Karunakaran‚ Nikil Ravi‚ Srinevasan MS Abstract-- Endodontic therapy is a treatment where the infected tooth s cavity is removed completely and filled with gutta-percha .During this therapy the size of the abscission in the root apex is important. If the abscission size is small the dentists call them lesion which can be easily removed during the therapy itself. But if it is large‚ the therapy

OBSERVATION The modicom 1 board‚ first in my observation is the power input these are the electrical input connections necessary to power the module. The LJ Technical Systems’ "I.C. Power 60" or "System Power 90" is the recommended power supplies. Then second is the sampling control logic is the circuitry generates the timing and control signals that sample the input waveform‚ and also creates a sinusoidal 1 kHz signal for use during the MODICOM 1 practical exercises. It is recommended that this

converted into binary strings‚ representative of their values. The process of conversion of analog signals into their equivalent digital form is termed analog-to-digital conversion. The reverse form of the process is digital-to-analog conversion. Often‚ computers utilize these important processes for control of analog devices. To that end‚ for analog-to-digital (A/D) and digital-to-analog (D/A) converters to be useful‚ there has to be a meaningful representation of the analog and signal quantity. Starting

Advantages of Digital Circuits Name: Instructor: Institution: Introduction Digital circuits are circuits that use signals in digital form instead of analog forms. One distinctive feature of a digital signal is that it assumes discrete values‚ most of the time two values. A digital signal takes time to change from one value to another‚ and assumes intermediate values during transmission (Verma). Steady values are slightly inaccurate. Voltages

Digital electronics‚ or digital (electronic) circuits‚ represent signals by discrete bands ofanalog levels‚ rather than by a continuous range. All levels within a band represent the same signal state. Relatively small changes to the analog signal levels due to manufacturing tolerance‚ signal attenuation or parasitic noise do not leave the discrete envelope‚ and as a result are ignored by signal state sensing circuitry. In most cases the number of these states is two‚ and they are represented by
