The minimum spectrum allocation required for W-CDMA is a. 5MHz b.2MHz c. 500KHz d. 100KHz

Questions 2. How can you improve the spectrum resolution? Dat TFT?

2-What is the maximum allowed frequency of the input information signal (modulator) in an AM system (DSB-LC) which has a bandwidth of 40kHz and a carrier frequency of 500kHz

In case of 625-B television standard the maximum frequency deviation should not exceed ± 50 kHz. Calculate the FM channel bandwidth required for audio signal if the highest frequency content in the miedolating signal is 10 kHz and significant sideband frequency components equal to 7.

Q2. A'single tone is modulated using WBFM transmitter. The total power is 450 watts into a 5 2 resistive load. Determine the minimum modulation index, where the average power of the second and third sidebands are equal. Under this condition determine: 1. The average power in all sidebands. 2. The ratio of the first sideband power to the total power. 3. The third sideband power, if the modulation index is reduced to maintain maximum first sideband power and keep wideband transmission.

ANSWER THE PROBLEM MAKE SURE THAT IT IS IN 4 DECIMAL PLACES: Solve for the side frequency volt, modulation depth is lessened by 25% of an AM transistor with 32V output voltage when modulated to a depth of 96%.
