Dear sir,
The applet you provided is extremely useful, I have just checked that after a long time. Thanks a lot.
I have one more query, I would appreciate your time.
The following text is not only defined in an weblink (i.e **broken link removed** ) , but also written in a number of other...
Hello Everyone!
About Amplitude Modulation, Usually it is seen in the book or web that (e.g. **broken link removed** )
'''' The message signal can be represented by m(t) = Mb cos(2πfb + φ)
and the carrier signal can be represented by c(t) = Ac cos(2πfc + φ),
Now Modulated signal =...
If you transmit an audio signal (e.g 20 Hz to 20 Khz ), why you keep considering about the speed of light? Isn't it perfect to consider only for electromagnetic waves?
Wavelength= Speed of light/ Frequency
should be used when we use an electromagnetic wave (e.g radio wave).
Please justify your...
Yah, I got you now. You and few like people are good only at memorizing some book staffs and always deliver those without understanding well the question. Both of your answers are known to all people, you dont need to teach us those. if you dont really know the answer , then its good not to...
Hej
When we need to know Sampling freq. value, which is, we know, equal to Fs= 2 * Max. Freq.
In such a case if we had known the value of highest harmonics, would the highest harmonics value equal to the Max freq. value for this problem?
HELLO
for CDMA (800 or 850 whatever you call), the total frequency range is:
824–849 MHz/869–894 MHz (uplink/downlink)
Consider either up-link or down-link, the total band is 25 MHz. We know CDMA use 1.25 MHz band, hence the number of total channel/band for either link should be (25/1.25) MHz=...
hello
From wiki..
''There are a fixed number of orthogonal codes, timeslots or frequency bands that can be allocated for CDM (Sync CDMA), TDMA, and FDMA systems, which remain underutilized (to fail to utilize fully) due to the bursty nature of telephony and packetized data transmissions. ''...
Hello
I understand the following question is very silly, however I am not sure about the answer.
Lets consider we are saying there is a signal with a frequency of 4 Hz (for example). In such a statement, does it mean the maximum frequency is 4 Hz for this signal? If it does, why we refer it as...
For Amplitude Modulation, it is understood that the bandwidth of a passband signal is always twice as much as that of a baseband signal, for example
if the bandwidth/max frequency of a message/baseband signal is 1 kHz and a carrier of 1 MHz is modulated with this baseband, then a "sum"...
