Relation between wave length and size of the antenna?
To decrease antenna height For transmitting a signal of wavelength λ the antenna height must be λ/4. So if we want to send a 1 Hz (λ=3*10^8 m) signal ( very very low frequency) using an antenna , its height must be 75,000 Km ( impossible to build such a huge antenna ). If the same signal is modulated to some high frequency say 88 MHZ ( λ = 3.4 m ) , antenna height needed is 0.8522 m (quite easy to construct !!! ) (88 MHZ is the starting range of Frequency modulation which exists upto 108 MHZ).
What are the difference between LCR meter and electrochemical impedance spectroscopy?
LCR meter is a device. And electrochemical impedance spectroscopy is a method. So the difference between them are like the difference between pen and writing.
What is impedance coupled amplifier?
The purpose of impedance matching is to provide for the highest efficiency between either the stages of an amplifier circuit or from a device to the amplifier for the same purpose. Impedance matching us used to make the circuits compatible based on electrical characteristics of a particular circuit from one section (or stage) to the next.
What is the difference between transmitting and receiving antenna?
There is no difference between the two.
Difference between hertz antenna and marconi antenna?
Hertz Antenna is lambda by 2 antenna & marconi antenna is lambda by 4 antenna...
What is the difference between an active antenna and a standard antenna?
An active antenna has a amplifier built in, a standard antenna does not. AKA powered antenna.
What is the advantages of buffer circuits in digital electronics?
buffer circuits helpful in overcoming the impedance matching problem.for example if we want to send a signal from one devise to other ,if there is no impedance matching between this two then signal is not transfered.now if we use buffer in between these two devises then the buffer without changing the signal shape or value it simply transffers the signal
What is impedance matching?
making impedances identical. when done between supply and load it is done to maximize power transfer. when done on cables and busses it is done to prevent or minimize signal reflections. a low impedance mismatch reflects an inverted signal, a high impedance mismatch reflects an inphase signal.
What is the Difference between 4 ohm to 8 ohm output?
There is really no amplifier on the market which has an output impedance of 4 ohms or 8 ohms. The impedance of an amplifier is always less than 0.5 ohms. We do not use matching, we use bridging when we connect the amplifier to the loudspeaker. Scroll down to related links and look at "Interconnection of two audio units".
What is the difference between Ohms and Ohms CT in impedance of an audio transformer?
The difference in between Ohms and Ohms CT is that in Ohms CT it has CT at the end.
What is the difference between an omnidirectional and an isotropic antenna?
An omnidirectional antenna can be practically implemented but an isotropic antenna cannot be implemented practically. An isotropic antenna resembles an ideal antenna with ideal values for all parameters.
How do you get sony ecm 200 mic to work with windows 7?
Most likely you will need a preamp or at least an impedance matching circuit between the mic and the mic in of the computer.
