    Question 1: Filters: It is also known as an electronic device, that where it is allowed or stopped unnecessary frequency or signals. And also it is Designed and developed to transmit frequencies in particular fixed range if needed. An also Filters also it alters the amplitude of signal it’s based on level of frequency. There are 4 types of filters: They are Low pass Filter: It’s a type of filter that which allows the signals which are lower and it will be cut- off by the frequency at certain time. High Pass filter It’s a type of filter that which allows the signals that are much greater than and also it’s cut off frequency at certain time.…

    1. Introduction The purpose of this experiment was to gain an understanding of how to use a signal generator, acquire data, understand the concept of a Low Pass Filter, gain knowledge of time domain sampling and sample rate, learn how to analyze and present data in MATLAB, as well as learn how to calibrate a microphone and record sound pressure data. To accomplish this the role of an electronics technician whose responsibility was to validate the performance of data acquisition equipment that…

    Considering it a relatively novel approach, there are two motives of using AWT, 1st; to validate the results of the earlier sections by employing a method without using any Fourier transform or filters, 2nd; AWT was found more straightforward application and a superior alternative of STFT providing satisfactory information of the T-F characteristics. Ref. [16] explained a comparison between STFT and AWT, shown in fig. 16. Instead of STFT with uniform T-F resolution, AWT does not compromise on…

    continued analyzing the aspects of the oscilloscope by considering the Bode plots of the AC- and the DC-coupled voltage output at various frequency as indicated in Figure 2. The experimenters believed the plots were reasonable Bode plots because the AC-coupled measurements are designed to accurately describe time-dependent signals, whereas DC-coupled measurements are designed to measure everything unselectively. As such optimizations are present, the AC should effectively express time-dependent…

    create distorted voltages and currents. Distortion of voltages and currents can impact on the power system adversely causing power quality problems. Therefore, approximation of harmonics is of high importance for efficiency of the power system network to maintain the quality limits recommended by standards to protect the sensitive loads, it is necessary to enclosed some form of filtering device to the power system. Harmonics are also increases overall reactive power demanded by equivalent load.…

    very essential for early detection of lung cancer [4]. Radiologists use CAD systems for preprocessing of the images and finding the most probable locations for lung nodules. First step in nodule detection is suppressing the background structure in lungs like ribs, bronchi and blood vessels. Then the nodules are classified based on size, contrast and shapes. Classification of nodules based on the above features produce a lot of false positives[3]. This paper proposes a CAD system which is fast…

    Stuidio) based on London, formed in 1969. VCS3 which was their first commercial synthesiser, main features are 3 controllable oscillators (VCOs), a noise generator, 2 inputs, ring modulator, low pass filter, reverberation level meter, trapezoid envelope generator, and stereo outputs. The another feature that stands out in this synth, is Matrix plugboard. This board has X and Y axis which corresponds to inputs and outputs. This matrix allowed musicians…

    robustness as well as imperceptibility as compare to spatial domain watermarking. Discrete wavelet transform (DWT): Wevelet is mathematical function that distribute data into different frequency component. The basic concept for DWT is when host data pass through low pass and high pass filter, it decompose the host signal into low frequency part and high frequency part. DWT decompose host data i.e image into four multi-resolution non-overlapped sub-bands namely Approximate sub-band(LL),…

According to Marc Rayman, “Framing Camera uses an f/7.9 refractive optical system with a focal length of 150 mm” (Ref 5). A charge-coupled device is a frame-transfer device that has a wider view to locate and map out the targeted bodies with its focal plane being at 1024 × 1024 sensitive and 93 rad pixels. Panchromatic which are black and white types of…
