What is the difference between fourier series and fourier transform with real life example please?
A Fourier series is a set of harmonics at frequencies f, 2f, 3f etc. that represents a repetitive function of time that has a period of 1/f. A Fourier transform is a continuous linear function. The spectrum of a signal is the Fourier transform of its waveform. The waveform and spectrum are a Fourier transform pair.
What happens when clipping occurs in a inverting amplifier?
The output waveform will be limited to the difference between the supply and ground (or between the positive and negative supplies). This causes distortion of the output waveform.
What is the difference between a positive limiter and a negative limiter?
The polarity at which it limits a waveform.
Which frequencies are the airband frequencies?
Airband, a group of frequencies in the VHF radio spectrum, uses the frequencies between 108 and 137 megahertz. A license is required to operate airband equipment.
What is the relation between sampling frequency and wave frequency?
There is no factual relation between these, but there is a common rule known as the Nyquist-Shannon theorem, that states that to reproduce a waveform with only reasonably errors, the sampling frequency must be at least twice the wave frequency.
What is the term for the distance between two sound frequencies or pitches?
The term for the distance between two sound frequencies or pitches is called "interval."
The time between any two similar points on an AC waveform is known as?
wavelength
What is difference between biphasic and monophasic defibrillators?
biphasic have lower waveform compared to monophasic
Do microwaves have higher frequencies than ultraviolet waves?
No, microwaves have lower frequencies than ultraviolet waves. Microwaves have frequencies between 300 MHz and 300 GHz, while ultraviolet waves have frequencies between 750 THz and 30 PHz.
Why two frequencies are used in dtmf?
The tone frequencies, are selected such that harmonics and intermodulation products will not cause an unreliable signal. No frequency is a multiple of another, the difference between any two frequencies does not equal any of the frequencies, and the sum of any two frequencies does not equal any of the frequencies.
What is the relationship between natural frequencies of an object and the harmonics that can be created in the object?
The natural frequencies of an object are the frequencies at which the object tends to vibrate easily. Harmonics are frequencies that are integer multiples of the fundamental frequency. When an object is excited at its natural frequencies, it tends to resonate and produce harmonics of those frequencies.
Difference between channel and bandwidth?
a channel is actually a path through which a signal of a particular frequency travels and bandwidth is the capacity of that path it tells about the number or range of frequencies which a path can carry
