used by various radio communication technologies. CDMA is an example of multiple access‚ which is where several transmitters can send information simultaneously over a single communication channel. 25. Draw the block diagram of a DSSS transmit-receive system. 27. Draw the block diagram of an OFDM transmission. 31. What is the digital data rate for AM digital and what is its comparable quality? The digital data rate for AM HD radio is 36 kbps‚ which produces an audio signal with comparable quality

The diagram indicates that the wave shape is not moving along the string but is only oscillating vertically on the string. [pic] Figure 1. A standing wave fixed at x = 0 and x = L. Five loops are shown. The frequency of a wave is given by [pic] (4) where V is the speed at which the transverse waves propagate along the string‚ The

The interview questions are always open ended. In order to create a good solid theory‚ usually they are based on the following: 1.What was the process? (Which is known as the core phenomenon) 2. What influenced the core process to occur? (Known as causal conditions) 3. What were the actions taken by the person in response to the process? (Strategies) 4. What were the outcomes or facts of these strategies? (Known as

4.4 Quadrature phase shift keying (QPSK) Quadrature phase shift keying (QPSK) has twice the bandwidth efficiency of BPSK since two bits are transmitted in a single modulation symbol. In the phase of the carrier takes on one of four equally spaced values‚ such as 0‚ π/2‚π and 3π/2‚ where each value of phase corresponds to a unique pair of message bits. The Quadrature phase shift keying (QPSK) signal for this set of symbol states may be defined as s_QPSK (t) =√(〖2E〗_s/T_s ) cos[〖2πf〗_c t +(i-1)π/2]

major control strategies discussed in this paper are: peak current‚ average current mode and borderline current control. These strategies are implemented in MATLAB/SIMULINK and the performance of the proposed converter is compared under open loop and closed loop operation. From the results‚ the input current waveform was close to sinusoidal implying high power factor and reduced harmonics for borderline control.
