  • How to Design Pulse Amplitude Modulation?

    Before we go into the design of pulse amplitude modulation let us know about the concept of modulation and different types of modulations. What is Modulation? Modulation is a process of changing the characteristics of a carrier signal like amplitude, frequenc

  • Who invented Antennas?

    There's no easy answer to that question because radio evolved into a useful technology through the second half of the 19th century thanks to the work of quite a few different people—both theoretical scientists and practical experimenters.

  • What are the Important Characteristics of the Antenna?

    Three features of antennas are particularly important, namely their directionality, gain, and bandwidth. Directionality Dipoles are very directional: they pick up incoming radio waves traveling at right angles to them. That's why

  • How long does an Antenna have to be?

    Most modern transistor radios have at least two antennas. One of them is a long, shiny telescopic rod that pulls out from the case and swivels around for picking up FM (frequency modulation) signals. The other is an antenna inside the case, usually fixed to the main circ

  • How does the Transmitter and Antenna Work?

    Imagine holding out your hand and catching words, pictures, and information passing by. That's more or less what an antenna (sometimes called an aerial) does: it's the metal rod or dish that catches radio waves and turns them into electrical signals feeding into something like a ra

  • What are Radio Waves?

    The basic building block of radio communications is a radio wave. Like waves on a pond, a radio wave is a series of repeating peaks and valleys. The entire pattern of a wave, before it repeats itself, is called a cycle. The wavelength is the distance a wave takes to complete one cy

  • The Three Distinct Features of Antenna You Need to Know

    Antennas come in a bunch of different shapes and sizes, but they’re all designed for the same purpose – to pick up a very specific radio wave frequency. You’ll find antennas ranging from the long metal wires sticking out from an FM radio to something rounder like a satellite dish, or

  • How does Radio Waves Work?

    Do you think sending a radio wave is a simple process of travel from point A to point B? But this isn’t always the case. Waves don’t always fly through the thin air straight from a transmitter to a receiver, and how they travel ultimately depends on what kind of wave fre

  • What is RF Communication – Protocol & Application?

    RF refers to the frequencies that fall with in the electromagnetic spectrum associated with radio wave propagation. RF current creates electromagnetic fields when applied to an antenna that propagate the applied signal through space. Electromagnetic wave based communications have been
