A 24 signal each of 5kHz base band bandwidth are FDM multiplexed using SSB sub carrier modulation. thecomposite multiplexed signal y(t) is frequency modulated using100MHz carrier frequency. the lowest frequencey of first channel ofthe multiplexed signal is20 kHz and no guard bands between thechannels, assume that each base band signal has th same normalizedpower. the channed with least noise has out put SNR of 50 dB.a) Find the output SNR of channels No. 10 and No. 24b) if the acceptable SNR is 35 dB how many channels in the system are usable
Two amplifiers(CS) connected in cascade. The input voltage to the first stage has a source voltage Vsig and Rsig= 100KOhm. Rv=10KOhm AND IS CONNECTED TO THE DRAIN OF THE SECOND STAGE. BOTH TRANSISTORS HAVE Id=.25mA and Vov=.25V
The battery is built by connecting several unit cells in series. Each unit cell has the voltage V1=1.4 V and the internal resistance Ri = 3.2 Ohm; 1) How many unit cells in series must the battery use to have the open-circuit voltage Vo.c. = 11.2 V
A series combination of two capacitances, valued 0.2 μF and 0.6 μF initially discharged, is charged to 10V. find the charge and energy stored in each capacitance.
A 5.88-g bullet is moving horizontally with a velocity of +340 m/s, where the sign + indicates that it is moving to the right (see part a of the drawing). The bullet is approaching two blocks resting on a horizontal frictionless surface.
Create the layout design for MOS NAND3 gate using a depletion-type transistor with VTL = -0.3V and enhancement-type transistors with VTO = 0.5V such that VOL is less than or equal to 0.1V. VDD = 2.5V , tox = 10nm and 2X = 0.6μm .
Derive equations for the capacitance, and resistance across the dielectric of a coaxial line of inner conductor radius a, and outer conductor radius b, and permittivity ε.
A full adder is a circuit which adds three bits X, Y, Z together and returns two bits C and S to represent the total as a 2-bit binary number C S. C is the MSB and S is the LSB. For example, if X=1, Y=1, Z=0, the total should be 2, or 102 in binar..
Provide an output V to indicate that at least one of the input ispresent. The input with the highest subscript number has thehighest priority. What will be the value of the four outputs if inputs D5 and D3 are 1 at the same time
An analog signal xa(t), band-limited to 5 Hz, is sampled at a rate of 10 samples per second to give a discrete-time signal x(n) = xa(0.1n). The discrete-time signal x(n) is then filtered with an digital FIR filter, h.
A system samples a sinusoid of frequency 480 Hz at a rate of 100 Hz and writes the sampled signal to its output without further modification. Determine the frequency that the sampling system will generate in its output.
Design a garage door controller using PLC Ladder Diagram (RSLOGIX 500 PLC SIMULATOR). The behavior of the garage door controller is as follows there is a single button in the garage, and a single button remote control.
The bandwidth of a series resonant circuit is 400 Hz. (a) If the resonant frequency is 4000 Hz, find Q. (b) If R = 10 ohm, what is the value of XL at resonance
