CELP coders implement a filter, the characteristics of which change over time, and they contain a codebook of acoustic vectors. Each vector contains a set of elements, where the elements represent various characteristics of the excitation signal. This approach is obviously far more sophisticated than a simple voiced/unvoiced flag. With CELP coders, all that is transmitted to the far end is a set of information indicating filter coefficients, gain, and a pointer to the excitation vector chosen. Because the far end contains the same codebook and filter capabilities, it can reconstruct the original signal to a good degree of accuracy. ITU-T Recommendation G.728 specifies a Low-Delay CELP (LD-CELP coder), which is a backward-adaptive coder because it uses previous speech samples to determine the applicable filter coefficients. G.728 operates on five samples at a time. In other words, the coder takes 5 samples (sampled at 8,000 Hz) and determines a codebook vector and filter coefficients to best match the 5 samples. The choice of filter coefficients is based upon previous and current samples. Because the coder operates on 5 samples at a time, we have a delay of less than 1 millisecond. Because the receiver also has access to the previous samples and can perform the same determination, all that is necessary to transmit is an indication of the excitation parameters. In fact, an index to the excitation vector is sent. Because there are 1,024 vectors in the codebook (and these are available at both the sender and receiver), the index is only 10 bits long. G.728 uses 5 samples at a time and these samples are taken at a rate of 8,000 per second. For each 5 samples, G.728 needs to transmit only 10 bits. A little arithmetic shows that G.728 results in a transmitted bit rate of 16 Kbps. The following text is taken directly from the G.728 specification and provides some further information on the coding mechanism. The text and the

When discussing the Six learner s goals, developers should help the Six clearly connect the key development motivators below to specific coaching goals. This link may be obvious to learners as they discuss why each coaching goal is important, but if it is not, developers can do one of two things: (1) Ask Six learners, What personal and professional benefits will you gain when you achieve this goal or (2) explain the connection between the goal and the motivator directly by saying, This will help you feel less anxious and trust yourself more.

1. Make sure your sensor is located near an AC receptacle. The leads from the sensor must be able to reach the receptacle. If it cannot reach one, you will have to splice additional wiring to the leads. 2. Strip the insulation from the sensor s wires. 3. Attach the contacts from your garage door sensor to the Powerflash device. 4. Plug the Powerflash into a wall receptacle. 5. Set the Powerflash to Mode 3, Input B (this configures the module so that a single device is turned on). 6. In the mudroom, plug a lamp into an X10 module. These modules sell for US$12.99 An example of a plug-in X10 module is shown in Figure 8-12.

The values defined by this enumeration are used to set or clear flags that control some of the ways information is formatted by a stream. The following describes each flag. When the skipws flag is set, leading white-space characters (spaces, tabs, and newlines) are discarded when performing input on a stream. When skipws is cleared, white-space characters are not discarded. When the left flag is set, output is left justified. When right is set, output is right justified. When the internal flag is set, a numeric value is padded to fill a field by inserting spaces between any sign or base character. If none of these flags is set, output is right justified by default. By default, numeric values are output in decimal. However, it is possible to change the number base. Setting the oct flag causes output to be displayed in octal. Setting the hex flag causes output to be displayed in hexadecimal. To return output to decimal, set the dec flag.

Use the method of cylindrical shells to calculate the volume enclosed when the curve y = x 2 , 0 x 3, is rotated about the x-axis (Fig. 8.20).
