Describe what happens when a typical AM modulator is overmodulated,and explain why overmodulation is undesirable.
The heating element in a soldering iron has a resistance of 30-ohm. Find the average power dissipated in the soldering iron if it is connected to a voltage source of 117 V rms.
1)How do you use the Cayley-Hamilton technique to find the state transition matrix and the state equation output y 2) How do you draw the standard form simulation diagram given a higher-order differential equation
The charge entering the + terminal of an element is q(t) =-12e^-2t mC. if the power delivered to the element is p(t) =2.4e^-3t W. Compute the current in the element, the voltage acrossthe element and the energy delivered to the element in the time..
Construct a nontrivial resistive circuit with at least two loops and at least three resistors in each loop. Verify Kirchho's laws for this circuit both theoretically and empirically. Notice that this item is more open-ended.
A pulse is used to measure the frequency response of a system. Since we expect the frequency response to extend to 20 kHz, select a pulse whose magnitude spectrum is constant within 1% out to 20 kHz.
Design a buffer circuit to measure the voltage on a small capacitor using a bipolar transistor and a DVM. Design a similar circuitusing a FET transistor. Which is better and why
The circuit will have as inputs a minimum of two inputs; the binary equivalent of two decimal numbers of not greater than (10,000)10. The circuit will produce a minimum of two outputs, the quotient and the remainder.
The film is developed with an overall gamma of 2, reinserted in the position of the film during recording and reconstructed using the same point source as that used to construct the hologram. Using laws of ray tracing of the hologram, find and cha..
a. build a k-map and obtain a simplified sum-of-products expressionfor F. It is not necessary to derive or show the truth table for F.b. Implement the function using exaclty four 2-input NOr gates. Donot use complemented inputs
Consider cold windy breeze parallel to your face, with an average facial dimension along the flow of 5 cm. The air velocity is 1 m/s (corresponding to 2.2 miles per hour). Assume laminar flow. 1) Calculate the thickness of the velocity boundary la..
A half wave dipole antenna is operating in air at a frequency of 100 MHz. At a distance of 1000 km and at an observation point ? = ?/2, electric field strength is measured to be 5 µV/m. Calculate the a. Length of the antenna
An engineer working in asatellite station complex has received the program by an earthstation and routed the signal through a rectangular waveguide ofdimensions (axb=2.4x1.2) to control room 12.2m away fromthe station feed horn.
