If the maximum IF deviation is 75KHz:
(i) What is the maximum output voltage of the Ratio Detector?
(ii) What is the minimum output voltage of the Ratio detector?
(iii) When the maximum discriminator output voltage is fed into an audio amplifier, the amplifier drives 100 Watts into an 8 ohm load? What is the dB gain of the audio amplifier?
The problem has two parts(a and b) and it asks: Find the power and rms value of each of the following signals: a) x(t) = 5 + Ccos(ωot+θ) b) x(t) = 2+7cos(1/2t+θ1)+3cos(2/3t+θ2)+5cos(6t+θ3)
A PWM is to be programmed to output a signal with a pulse high width of 150 usec and a pulse low width of 250 usec. What are the values required for prescale (if any) PWMPER and PWMDTY An 8-bit configuration is used and the E-clock is 24 MHz.
The phase margin needs to be at least 45 degrees. The error for a ramp input should be less than 5% Add the lag compensator using bode plots. Show the characteristics (margins) of uncompensated and compensated system to
For a complex load of 100 + 25 j ohm. find the matching circuit consist of ideal capacitor and/or inductor to match the load to 50 ohm impedance at 500MHz. The solution should include circuit schematic and values of each component
Let us assume that a synchronouse 3 phase alternator produces a no-load line voltage of 13.2 KV. if a load having a lagging power factor of 0.8 is connected to the machine, must the excitation be increased or decreased
a plane wave is obliquely incident onto the planar interface between mismatched, lossless, nonmagnetic, uniform media, yet undergoes no reflection. If incidence is at 54 degrees to the normal, at what angle to the normal does the transmitted wave ..
Using 4-bit numbers to save space, multiply 3ten x 4ten in binary.
A certain three-port network is lossless and reciprocal, and has S13 = S23 and S11 = S22. Show that if port 2 is terminated with a matched load, then port 1 can be matched by placing an appropriate reactance at port 3.
Characteristics of a filter, A filter has the following characteristics: Attenuation = 3.0 dB from 0 Hz to 2 kHz. From 2 kHz to 20 kHz attenuation increases from 3 dB to 23 dB in a straight line when plotted on axes of power in decibels (vertical a..
For the discrete signals defined as the following: x[0]=4, x[1]=1, x[3]=-1, x[n]=0 for all other integers n. v[0]=1, v[1]=-2, v[2]=3, v[3]=-4, v[n]=0 for all other integers n. Compute the convolution x[n]*v[n] for n
