Demodulators for FM
Figure shows a block diagram of a general FM demodulator, which is implemented by generating an AM signal whose amplitude is proportional to the instantaneous frequency of the FM signal, and then using an AM demodulator to recover the message signal. Transforming the FM signal into an AM signal can be achieved by passing the FM signal through an LTI system whose frequency response is nearly a straight line in the frequency band of the FM signal.
FM demodulators mainly fall into two categories: frequency discriminators and locked-loop demodulators. While both give the same performance for relatively high signal levels, locked- loop demodulators provide better performance than the discriminator when signal levels are low and noise is a problem. The discriminator produces an output voltage proportional to the frequency variations that occur in the FMsignal at its input. Locked-loop demodulators are more cost-efficient when implemented in IC form.
#I need some guides in order to build a circuit that will be beneath a machine and turn that machine left/right/up/down
Q. Explain phase-shift keying? In PSK, the phase angle of a carrier is keyed between two values. When the values are separated by π radians, it is known as phase-reversal keyin

You have a motor that is powered by 24 VDC. It free-runs at 600 radians/second, and stalls with a load of 125 in-lbs. The time constant (τ) of the motor itself is 1.5 seconds. T
Give the register organization of 8257? The 8257 do the DMA operation over four independent DMA channels. Each of the four channels of 8257 has a couple of two 16-bit registers
What makes them sine? Ans) Fourier tells that only a sine wave has no harmonic content. The math works out that if you have any wave shape other than a sign wave, you can brea
