Modern SIM cards allow applications to be loaded when the SIM is in use by the subscriber. These applications communicate with the handset or a server using SIM application toolkit, which was initially specified by 3GPP in TS 11.14 (there is an identical ETSI specification with different numbering).
(Redirected from Voltage follower) A buffer amplifier (sometimes simply called a buffer) is one that provides electrical impedance transformation from one circuit to another. Two main types of buffer exist: the voltage buffer and the current buffer.
Line voltage is rectified, filtered and converted to a. variable voltage and frequency. When frequency-converter ouput is connected to an AC motor, it's possible to adjust motor speed. When an AC drive is used to adjust motor speed, motor slip is no longer a problem in many. applications.
