design an Armstrong indirect FM modulator to generate an FM carrier with a carrier frequency of 96 MHz and Df= 20 kHz. A narrow-band FM generatorwith fc = 200 kHz and adjustable Df in the rangeof 9 to 10 Hz is available. You are also provided with anoscillator with adjustable frequency in the range of 9 to 10 MHz.There is a bandpass filter with any center frequency, and onlyfrequency doublers are available.
A potentiometer with a total range of 350° is supplied with a voltage of 12 Vdc. Find the output voltage for an angle of 135°. An absolute optical rotary encoder has five tracks. How many bits is the output
A 6 pole, 60 hz induction motor is wye connected and has a rated slip of .03 with the follwoing parameters: Rs=0.5 ohms, Rr'=0.3ohms, Xs=J1 ohms, Xr'=J0.35 ohms, Xm=j20 ohmsand the total rotational losses=7300 watts.
The student turnsaround and travels half the distance between his current location and his home beforechanging his mind again. This process of changing direction and traveling half the remainingdistance continues until the student reaches a certai..
Design a CE amplifier with gain of 10 using a 2N3906 transistor and a 20V power supply. Calculate the required resistor and capacitorvalues for the circuit, assuming a minimum frequency of 10 Hz.
Use a JK Flip Flop 74LS112 Chip and a NOT gate to design a D Flip Flop and using that D Flip Flop and designa shift register. Draw the circuit diagram of the shift register and the truth tables JK, D flip flops and shift register.
a Three phase to single phase converter employs a 6 pulse bridge circuit. This device is fed from 400V,50 Hz supply through adelta/stare transformer whose per phase turns ratio 3:1. For an output frequency of 2Hz, the load reactance is w0L =3ohm.
Design an analog computer circuit (using minimum resistor values of 10 k ohms ) to obtain the summing (adder) function. Vo = -v1 -v2 +v3
The treasure map in the figure gives the following directions to the buried treasure: "Start at the old oak tree, walk due north for 530 paces, then due east for 130 paces. Dig." But when you arrive, you find an angry dragon just north of the tree..
Add an activehigh overflow indicator and the required detection circuitry. Thecircuit should have inputs a7 through a0, inputs b7 through b0, sumoutputs s7 through s0, and output overflow. For all inputs/outputsuse index 7 as the MSB and index 0 a..
A circular loop TV antenna with 0.01 m2 area is in the presence of a uniform -amplitude 300 MHz signal. When oriented for maximum response, the loop develops an emf with a peak value of 20 mV. What is the peak magnitude of B of the incident wave?
Write a short report that analyses the P&ID - Basic Neutralizer Control System: The neutralizer process may be used to adjust the pH of a feed stream.
