discuss how the information signal is recovered from an FM signal using slope detector

In a superheteridyne receiver, what is the value of the image frequency if a 580 kHz channel is being selected and IF frequency is 455 kHz?

1)What is the principle of IR Spectroscopy? 2)How many types of bending vibration? The number of species? 3)Why KBr used in IR spectroscopy? 4)Why water is not used in IR spectroscopy? 5)Does Infrared have color?

Please discuss an aspect of the weighting function for the array elements.

if the natural frequency of a pll is 5 MHz, adn the upper pull in range is 5.1 MHz, determine the width of the capture range5.2 MHz5.1 MHz 0.1 Mhz 0.2 MHz None of the choices

Explain the concept of dispersion in optical fibers and its impact on the quality of signal transmission.

3. The external power efficiency of an InGaAsP/InP planar LED is 0.75% when the internally generated optical power is 30 mW. Determine the transmission factor for the InP-air interface if the drive current is 37 mA and the potential difference across the device is 1.6 V. The refractive index of InP may be taken as 3.46.

#3 answer the question!

The focal plane of the OLI instrument on Landsat-8 is roughly 7,000 pixels wide. It consists of 14 detector modules (each 500 pixels wide). Why does the sensor use 14 detector arrays to span the 7,000 pixel width rather than one long array? A. The instrument measures 14 spectral bands, and each one uses a different module. B. It is easier and cheaper to manufacture multiple small arrays rather than one large array. C. Using 14 small arrays provides better spatial resolution than using one large array. D. It is easier to meet the cooling requirement when the focal plane array is divided into smaller pieces.
