  • Dual

    By supplying separate wireless interfaces for each band, dual-band 802.11n and 802.11ac routers provide maximum flexibility in setting up a home network. Some home devices require the legacy compatibility and greater signal reach that 2.4 GHz offers while others may require the additional network bandwidth that 5 GHz offers.

  • What is the difference between DSB

    Jun 15, 2017With simple logical thinking you can infer that sideband is enough to retrieve the message signal. So we have three kinds of AM transmission: Single Side Band(SSB) where only one sideband is transmitted. Double Sideband Suppressed Carrier(DSB-SC)

  • The use and advantages of CBD patches in alleviating pain

    1 The use and advantages of CBD patches in alleviating pain. The CBD oil is made from extracting the cannabinoid from the cannabis plant and then diluting it with a carrier oil which can be either hemp seed oil or coconut oil. A CBD patch is a transdermal band aid like a piece of plastic which contains the cannabinoids. A person can apply the

  • Television Frequencies

    The 8-VSB modulation used in ATSC (DTV) has a pilot carrier that serves as a reference frequency for DTV receivers and can be heard on an AM or FM receiver. The pilot carrier is approximately 310 kHz (.31 MHz) above the lower band edge. The exact frequency used may vary because the transmitted signal may be offset slightly to reduce interference.

  • Modulation Techniques

    Aug 28, 2015Advantages of Modulation: Avoid mixing of different frequency signals and increase the range of communication i.e. without modulation, we can transmit the message up to 100 meters and with modulation, we can transmit the message up to 150 meters. Allow the flexibility for adjusting the bandwidth. In the definition,

  • Block diagram of AM transmitter and receiver with explanation

    Apr 11, 2015Block diagram of AM transmitter and receiver with explanation (SW) frequency bands for AM broadcast. The MW band has frequencies between 550 KHz and 1650 KHz, and the SW band has frequencies ranging from 3 MHz to 30 MHz. The advantages of the synchronous AM detector are that it provides a far more linear demodulation performance and it

  • Music

    Some people say that a swinging rhythm happens when all the jazz musicians start to feel the same pulse and energy from the song. If a jazz band plays very well together, people will say that is a swinging jazz band or that band really swings well. Jazz influenced other types of music like the Western art music from the 1920s and 1930s.

  • Power Line Carrier Communication

    Operating Principle. A power line modem not only modulates the data to transmit it over the power lines and but also demodulates the data it receives from the power lines. By using modulation techniques, binary data stream is keyed on to a carrier signal and then coupled on to the power lines by PLM.

  • Superheterodyne Receivers

    1. Know how a superheterodyne receiver works and what its advantages are. What Heterodyning is. To heterodyne means to mix to frequencies together so as to produce a beat frequency, namely the difference between the two. Amplitude modulation is a heterodyne process: the information signal is mixed with the carrier to produce the side-bands.

  • Single Side

    The carrier signal is present even if nothing is being transmitted Single Side-Band . The concept of single side-band (SSB) is very simple: if you don't need two side-bands, get rid of one! To make that happen, you merely add a component to your system that removes the extra side-band. That component is called a band pass filter.

  • Advantages and Disadvantages of ISM Band Frequencies

    Oct 22, 2013Advantages and Disadvantages of ISM Band Frequencies. The 5 GHz frequency is often used in commercial WiFi applications. Many times it is used as a backhaul link connecting two 2.4 GHz systems over some distance. 5 GHz is also the frequency used for the emerging standard 802.11ac which will provide up to 1.3 Gbps of wireless data throughput. Additionally 802.11n can use the 5 GHz

This transition from conduction band to valence band involves photon emission (takes care of the principle of energy conservation). This is known as direct recombination. Direct recombination occurs spontaneously. GaAs is an example of a direct band-gap material.

  • Carrier recombination and generation

    Band-to-band recombination depends on the density of available electrons and holes. Both carrier types need to be available in the recombination process. Therefore, the rate is expected to be proportional to the product of n and p. Also, in thermal equilibrium, the recombination rate must equal the generation rate since there is no net recombination or generation.
