A new phone company wants to provide very cheap voice-only cell phone capability to 200,000 simultaneous users in San Francisco. They transmit only 8kbs per duplex channel using FDMA (frequency division multiple access) and BPSK (1 bit/Hz).
A CB amplifier is operating with Rl = 10 kohm, Rc = 10 kohm, and Rsig = 100 ohm. At what current Ic should the transistor be biased for the input resistance Rin to equal that of the signal source
A sinusoidal message signal has a frequency of 10 Hz. The signal is the input to an FM modulator with an index of 8. Determine the bandwidth of the modulator output if a power ratio, Pr = 0.8 is required.
The nameplate on a 50-MVA, 60-Hz single-phase transformer indicates that it has a voltage rating of 8.0-kV: 78-kV. An open-circuit test is conducted from the low-voltage side, and the corresponding instrument readings are 8.0kV, 62.1A, and 206kW.
design and construct a circuit for a cookie vending machine. The machine sells cookie for 75 Yen each. Assume that there are only 25, 50, and 100 Yen coins. Three different types of coins can be denoted by three different switches on the board, re..
