A stepper motor is a polyphase AC synchronous motor (see Theory below), and it is ideally driven by sinusoidal current. A full-step waveform is a gross approximation of a sinusoid, and is the reason why the motor exhibits so much vibration. Various drive techniques have been developed to better approximate a sinusoidal drive waveform: these are half stepping and microstepping.

Before you disconnect anything, make absolutely sure you know how to put it back. Number both sides of each connection with labels made of masking tape. If necessary, make drawings of cable routes and how clips fit. Use a craft knife or razor blade to cut away the wrapping from the damaged section. Take care not to cut into the plastic cable insulation.

Dithering the stepper signal at a higher frequency than the motor can respond to will reduce this "static friction" effect. Because windings are better utilized, they are more powerful than a unipolar motor of the same weight. This is due to the physical space occupied by the windings.

I think that this approach results in an easier design process and a better board. The AWG layout progresses from left to right: from power input and communication input/output, to the power supply circuitry, to the processor, to the DAC (which is controlled by the processor and constitutes the board’s transition from digital to analog), to the analog signal-conditioning circuitry, and finally to the output connector. Parts that don’t have a specific position in the functional flow—such as the oscillator (U4), the DAC’s passives (C16, R5, etc.), and the voltage reference (U3)—are arranged near the components that they support.

Since the finite-impulse-response (FIR) filtering is a common operation in DSP, we will continue our discussion based on examining the difference equation of an FIR filter. This simple example will show the typical properties of many DSP algorithms. After reviewing the problem of handling the incoming samples, we will discuss the circular buffering as an efficient solution to the problem.

Panelization is the arranging of arrays of multiple PCBs onto a single substrate that fits in the standard processing machine. A panel may hold multiple boards with similar or different sizes and shapes. This method is faster and less costly compared to the fixtures, which require a custom carrier for every new PCB design.

When the clutch pedal is released, the thrust bearing is withdrawn and the diaphragm-spring load once again clamps the driven plate to the flywheel to resume the transmission of power. Some cars have a hydraulically operated clutch. Pressure on the clutch pedal inside the car activates a piston in a master cylinder, which transmits the pressure through a fluid-filled pipe to a slave cylinder mounted on the clutch housing. The slave-cylinder piston is connected to the clutch release arm.

The steam engine uses mechanical governors; another early application was to govern the speed of water wheels. Prior to World War II the constant speed propeller was developed to control engine speed for maneuvering aircraft. Fuel controls for gas turbine engines employ either hydromechanical or electronic governing.
