In the case where high speed differential signals are transmitted in differential transmission lines through via holes with open-stubs, signal waveforms are distorted due to impedance mismatch in the open-stubs of the via holes, thus causing jitter, which has become an issue of high speed signals. For differential transmission lines that pass through via holes with open-stubs, a degree of coupling of the lines is decreased while the differential characteristic impedance is made constant. Thereby, the effects of backward cross talk noise caused by the coupling can be minimized, and thus jitter can be suppressed.

A motor control system for a two-phase brushless DC motor uses measured EMF voltage from the passive set of stator coils to control commutation. A microcontroller receives the EMF voltage measurement and compares it to a threshold voltage value, which may be speed-dependent for advance commutation at high motor speeds. A match of the EMF voltage measurement with the threshold value triggers commutation of the drive to the opposite set of stator coils. The microcontroller also has an up-down counter timer whose count value is compared to an external speed reference. Each match of the count value triggers a transition in a pulse-width modulated (PWM) drive signal. The duty cycle of the PWM signal establishes an average drive voltage that controls motor speed.
