Armenia Description. Armenia is a mountainous, landlocked country, on the southeastern edge of Europe, and at the gateway to the Middle East and Asia. This valuable geographical position for potential trade between continents became a curse of sorts.istorically Armenia and Azerbaijan have been long associated with Asia and the Middle East. In recent years some sources now consider them to be more closely aligned with Europe based on their modern economic and political trends. I.E.
Pulse-position modulation (PPM) is a form of signal modulation in which M message bits are encoded by transmitting a single pulse in one of possible required time-shifts. This is repeated every T seconds, such that the transmitted bit rate is bits per second.
Guide to PWM and PPM PWM and PPM are two common words used in the R/C industry. PWM stands for Pulse Width Modulation and PPM stands for Pulse Position Modulation. Some devices that use PWM for control are ESC's (electronic speed controls) and servos.he same data can be packed into a PPM frame and only take 20ms per update. Transmitters and receivers are the two most common R/C devices that use PPM. The following are lists of common devices that use PPM and PWM. R/C Devices that use PWM Pulses: 1  Servos. 2  Electronic Speed Controllers. 3  R/C switches. 4  R/C lights.
