Using the same message signal and value for fm used in the preceding computer exercise, show that carrier reinsertion can be used to demodulate a SSB signal. Illustrate the effect of using a demodulation carrier with insufficient amplitude when using the carrier reinsertion technique.
A switch-tail counter (also called twisted ring counter, Johnsoncounter) uses the complement of he serial output of a right shiftregister as its serial input. a) Starting from an initial state of 000, list the sequence of the states
Data at a rate of 2 Mbps is to be transmitted via a pass-band communication system whose carrier frequency is 500MHz. A binary antipodal system with roll-off factor of 0.2 is used for this communication. The AWGN single-sided power spectral densit..
a) Design a circuit with a single opamp to realize V0=V1-4V2, where V1 and V2 are two input voltages. b) Select the resistor values so that no more than .25W is dissipated in any resistor when the input voltages are no larger than 10V
In addition, you have a 32-Kbyte Flash chip, a 16-Kbyte SRAM chip, and a 16 KByte DPRAM chip. You want to locate the FLASH chip right in the beginning of the address space, the SRAM chip just after it, and the DPRAM at the end of the address space..
A 3-phase 230 V, 9 kVA, 0.9 PF (lagging) load is supplied by 10 kVA, 1330/230 V, 60 Hz three-phase transformer connected in Y-?. The equivalent impedance of transformer referred to the low-voltage side is 0.12 + j0.25.
The all-aluminum conductor (AAC) identified by the code word Bluebell is composed of 37 strands, each having a diameter of 0.1672 in. Tab les of characteristics of AACs list an area of 1 ,033,500 emil for this conductor (1 emil = (π/4) X 10-6 in2)..
I read about some parameters estimation toolbox in SIMULINK but I couldn't understand it well. I knew that it can find the parameters of a motor using measurements data. I watched also some videos explaining that. However, this is not enough to un..
A radio receiver for the HF band covers the frequency range 2 MHz to 30 MHz. The first IF frequency is 3.0 MHz and the local oscillator is above the received signal frequency.
Please explain Active, Reactive, Apparent and Complex Power .(Explanation with formulas Required)
let X(s) be the Laplace Transform of signals that are bounded (i.e. the poles of X(s) are on the left-hand s-plane). Find lim [as t goes to infinity)] y(t). Determine if the system is BIBO stable. If not, determine what makes the system unstable.
The value of the capacitor from the high-voltage terminal to the tap point is 0.005µF. The tap point voltage is 4 kV. What is the value of the capacitor connected between the tap point and the ground terminal. What is the value of the tuning induc..
1) If we did not use the two's complement system, how would we do subtraction? 2) How is overflow different from carry?
