Problem 5 The configuration shown below depicts two vertically oriented half-wave dipole antennas pointed towards each other, with both positioned on 100-m-tall towers separated by a distance of 5 km. If the transmit antenna is driven by a 50-MHz current with amplitude Io 2 A, determine: Reflecied 100m (a) The power received by the receive antenna in the absence of the surface. (Assume both antennas to be lossless.) (b) The power received by the receive antenna after incorporating reflection by...

Problem #2: (40 points) Consider the following communication link. Both the transmitter and receivers are properly matched to their respective antennas. Assume that the system nominal temperature is 290 K. A detailed block diagram of the receiver is shown in the figure Determine 1. The effective isotropic radiated power in dBm. 2. The space loss in dB 3. The communication link total losses in dB 4. What would be the received power at the receiver input in dBm? 5. What's...
A water tower is fed from an underground water source (Figure 2). The difference in level is 67 m. The flow of water must be at least 55 m'/h. To provide this flow (55m/h), a pump must be driven...
A water tower is fed from an underground water source (Figure 2). The difference in level is 67 m. The flow of water must be at least 55 m'/h. To provide this flow (55m/h), a pump must be driven at a speed of 690 RPM. It can turn faster, but without exceeding 900 RPM. Its efficiency is 81%. The pump is driven directly, therefore without gearbox, by an asynchronous motor, which itselif is supplied directly by the 400V/50 Hz three-phase...

Data Analysis Project Part 1Custom Fabric Ventures is a small company that
produces fabric-based wardrobe accessories (such as, handbags,
scarves, and headbands) and home accessories (such as placemats,
pillows, and window treatments). The company keeps a
limited number of popular items in stock, but primarily produces
custom orders. Customers are able to choose from a wide selection
of styles, sizes, and fabrics for each type of product. Most of the
company’s customers are small boutiques, home décor shops, and
home-decorators...
