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 signal is used for most of the experiments‚ as you will find that it is difficult to synchronize more than one oscilloscope trace when the input comes from an external source. Then third is the sampling circuit is the signal at the ANALOG INPUT socket is sampled at a rate‚ and for

first look at this form of transmission. An analog wave form or analog signal is characterized by being continuously variable along amplitude and frequency. Digital signal is quite different from an analog signal. The signal is much simpler. Rather than being a continuously variable wave form‚ it is a series of discrete pulses‚ representing one bits and zero bits. See the figure below to look at analog and digital signals. The way ones and zeros are physically carried through a specified

pulse-code modulation and digital signals for sound reproduction. This includes analog-to-digital conversion (ADC)‚ digital-to-analog conversion (DAC)‚ storage‚ and transmission. In effect‚ the system commonly referred to as digital is in fact a discrete-time‚ discrete-level analog of a previous electrical analog. While modern systems can be quite subtle in their methods‚ the primary usefulness of a digital system is the ability to store‚ retrieve and transmit signals without any loss of quality.

In this paper the Forgetting Factor RLS (FFRLS) approach has been considered to estimate not only voltage sag‚swell‚momentary interruption but also the amplitudes and phases of harmonics in case of time varying power signals in presence of White Gaussian Noise. Also comparison results with LMS and NLMS algorithms are presented to show the effectiveness of the proposed RLS algorithm. Keywords- RLS‚ LMS‚ NLMS‚ Harmonic Estimation‚ White Gaussian Noise I.

In this analysis‚ the stator current signal transformed to the frequency domain using a FFT algorithm. The stator current signal of the motor is used to analyze and detect specific fault frequencies related to incipient faults. For stator winding fault‚ there is an associated fault frequency that may be identified in the spectrum. The stator fault has been detected by comparing the healthy power spectrum to faulty power spectrum. The power spectrum of stator current for healthy no-load condition

This is because the polarity of the carrier will affect the flow of modulating signal through the diodes. The outputs are made up of two signals‚ one signal shifted up by carrier frequency signal and the other signal is shifted down by frequency carrier. Balanced ring modulators are widely use in musical instrument like guitar and radio receivers. Keywords— balanced ring modulator‚ modulating signal‚ carrier signal‚ output waveform‚ amplitude I.
