In direct sequence spread spectrum, the torrent of information to be transmitted is divided into small pieces and each allotted across to a frequency channel across the spectrum (Rouse, 2015). An informational signal at the point of transmission is added with a higher data-rate bit sequence, which is referred to a chipping code that splits the information by way of a spreading ratio (Rouse, 2015). This redundant chipping code provides the signal the ability to resist interference and also allows the original information to be recovered if informational bits are damaged during transmission (Rouse,

The authoritative amplifier section has 7 separate output stages with equal circuit topology, with every channel rated at 125W, to easily drive modern loudspeakers.

The objective of this lab is to learn how to use the Tutor TIMS software to build and analyze a communication system. This lab required us to use Audio Oscilloscope, Adder and Tuneable LPF in order to get the required frequency signals.

The COM-3011 operates by first mixing the received signal with 125 MHz, thus the data is now contained on it. The centre frequency is chosen by mixing a user specified radio synthesiser frequency with the 125 MHz together. For example to obtain a centre frequency of 100 MHz, the user would specify 225 MHz or -25 MHz. The bandpass filter will reduce the bandwidth to 40 MHz or 20 MHz either side of centre frequency [12]. This sample is the duplicated and the second part delayed by 90 degrees to form an in-phase and quadrature features.

In the underlay approach, secondary users should operate below the noise floor of primary users, and thus severe constraints are imposed on their transmission power. Ultra-wideband (UWB) technology is very suitable as the enabling technology for this approach. In spectrum overlay CR, secondary users search for unused frequency bands, called white spaces, and use them for communication.

You are sacrificing a more spread out coverage area for the ability to shoot a narrow RF beam over a greater difference, lending more stability and higher possible speeds to your WLAN. Week2: Relationship Characteristics Checkpoint

The frequency for DSSS channels in 802.11b is the 2.4 GHz frequency range. It is largely shared by many technologies (Bluetooth, cell phones, wireless LANS, etc).

It has a 100 dB input sensitivity. Its output voltage is 50 kOhm. It operates at a frequency response of 20 to 20,000 Hz at 1 volt and 1 kOhm of impedance. At these specifications, you can use this Sony with your preferred speakers, receivers, and

The Style SweeperTM 3-band EQ can dial in precise frequencies and gives the player more freedom to tailor the well-balanced tones of the pickups to his or her liking. This is done by means of the 4 knobs on the face of the bass - Volume, Style Sweep / Finger Slap, Balance, and Treble / Bass Boost and Cut. The EQ is powered by an easy-access 9V battery box on the rear of the

This left the Subkick and M88 for the author to work with. The kick was gated and then compressed, so the compressor did not reduce the transient peaks that the gate would detect. The kick had -4dB of compression because it was quite inconsistent in terms of dynamics. After this was applied, throughout the song the kick had a tendency to poke out here and there. The author used a limiter to correct this problem and to reduce the kicks dynamic range even further.

On these tracks, I set the makeup gain to approximately +5.0 dB in order to give certain instruments more presence in the recording. There was also considerable distortion in the last note of the chorus, so the use of the threshold of compressor also minimised this. A compressor diminishes the dynamic range of a signal and allows you to increase the overall volume. There are six major components of a compressor: the threshold, ratio, attack, release, gain and hard or soft knee. The threshold refers to the level in which the compressor begins to act upon the signal, and the ratio is the amount that the compressor affects the signal. The ratio is portrayed as a proportion such as 3:1, which means that if the input level is 3 dB over the threshold, the output signal will be reduced to 1 dB. The highest ratio is ∞:1, which is known as a limiter, which is also efficiently done at a ratio of 60:1. A limiter brings any signal over the threshold to be brought done to the threshold level, with the exception of sudden increases in the input loudness. The attack controls how soon the compressor kicks in, the release controls how long the compressor continues affecting the signal after it has dropped back below the threshold, and the gain allows you to adjust the level of the signal going out of the compressor. Hard or soft knee are both angles of compression and its desired

The Loudness button on consumer stereo receivers is an equalization circuit that boosts the highs and lows as the volume is lowered so the music will sound the same whether soft or loud. Noise-shaping circuits filter dither and quantization noise into the extreme upper range, where we will simply notice it less.

Wireless networking hardware requires the use of underlying technology that deals with radio frequencies as well as data transmission. The most widely used standard is 802.11 produced by the Institute of Electrical and Electronic Engineers (IEEE). This is a standard defining all aspects of Radio Frequency Wireless networking

Advanced Micro Devices (AMD) is a customer-oriented company that manufactures computer processors and memory chips and supplies its products to various technological companies worldwide. This corporation’s overall strategic objective is to be “more efficient, more responsive, and intensely focused on delivering innovative solutions that its customers want and need to succeed” (Syed, 2006). AMD has become a leader in customer relationship management through its Customer-centric Innovation philosophy. This philosophy focuses on three major components—differentiation, solutions, and connections. According to Abdul Samad Syed, AMD’s main goal of this customer relationship model is to, “help customers achieve results by giving them differentiated products and services, enabling complete solutions with our ecosystem partners, as opposed to point technology and collaborating efficiently by sharing customer data with our connections” (Syed, 2006). This philosophy is what makes AMD’s customer relationship management superior to its competitors and truly gives the company a competitive advantage in the tech industry.
