Radio frequency (RF) is a measurement representing the oscillation rate of electromagnetic radiation spectrum, or electromagnetic radio waves, from frequencies ranging from 300 gigahertz (GHz) to as low as 9 kilohertz (kHz). With the use of antennas and transmitters, an RF field can be used for...
By calculating the inverse of the time-period, the frequency of the wave would be obtained.Answer and Explanation: Given Data The time period of periodic wave is {eq}T = 0.28\;\sec {/eq}. The formula to calculate the frequency of wave is given by, {eq}f =...Be...
What is Frequency? Electrical Alternating current (ac) frequency is the number of cycles per second in an ac sine wave. Frequency is the rate at which current changes direction per second. Frequency is measured in hertz (Hz), an international unit of measure where 1 hertz is equal to 1 ...
The wave length range of the visible spectrum extends from violet (4... 02:01 A FM radio station broadcasts at frequency of 103.1 MHz . What is the ... 01:26 The Vividh Bharti station of All India Radio , Delhi, broadcasts on a... 01:22 The threshold frequency v(0) for a meta...
Electromagnetic Wave:Examples of electromagnetic radiation (light) include visible light, ultraviolet light, x-rays and microwaves. They all behave like periodic waves. Therefore, there is a wave shape with a certain length that repeats over time. The frequency is the number of times t...
(RF) transmissions. Since the technology continues to improve, radio frequency integrated circuits (RFICs) have become complex chips both by themselves and integrated into very largesystem-on-chip (SoC)solutions. An RFIC is designed to operate at high frequencies, typically in the range of ...
The frequency of a wave can be calculated using the formula f = 1/T, where f represents frequency and T represents period. In this case, with a period of 6 seconds, the frequency would be f = 1/6 = 0.1667 Hz. This means that the wave completes 0.1667 cyc
To use an op-amp at high frequency, it is necessary to take two factors into consideration: slew rate and Unity Gain Cross Frequency (fT). If the slew rate is low for the frequency used, the square wave will become a trapezoidal wave and the sine...
Radio waves:Radio waves are electromagnetic waves whose wavelength is more than the infrared rays. Therefore, the frequency of the radio waves is less than that of the infra-red rays. Wave Travel:The wavelength of a wave, λ (m), is the distance the wa...
