Other types of lossy compressors, such as the linear predictive coding (LPC) used with speech, are source-based coders. These coders use a model of the sound's generator (such as the human vocal tract with LPC) to whiten the audio signal (i.e., flatten its spectrum) before quantization. LPC may be thought of as a basic perceptual coding technique: reconstruction of an audio signal using a linear predictor shapes the coder's quantization noise into the spectrum of the target signal, partially masking it.
What is thought of as a basic perceptual coding technique?
****
The answer: linear predictive coding

Another common application is the control of the throttle of an internal combustion engine in conjunction with an electronic governor. In this usage, the motor works against a return spring to move the throttle in accordance with the output of the governor. The latter monitors engine speed by counting electrical pulses from the ignition system or from a magnetic pickup and, depending on the speed, makes small adjustments to the amount of current applied to the motor. If the engine starts to slow down relative to the desired speed, the current will be increased, the motor will develop more torque, pulling against the return spring and opening the throttle. Should the engine run too fast, the governor will reduce the current being applied to the motor, causing the return spring to pull back and close the throttle.
What is a governor connected to?
****
The answer: return spring

In 1998, Democratic voters dominated areas of the state with a high percentage of racial minorities and transplanted white liberals from the northeastern United States, known colloquially as "snowbirds". South Florida and the Miami metropolitan area are dominated by both racial minorities and white liberals. Because of this, the area has consistently voted as one of the most Democratic areas of the state. The Daytona Beach area is similar demographically and the city of Orlando has a large Hispanic population, which has often favored Democrats. Republicans, made up mostly of white conservatives, have dominated throughout much of the rest of Florida, particularly in the more rural and suburban areas. This is characteristic of its voter base throughout the Deep South.
