A condition in an amplifier, caused by over driving one or more stages, in which the amplifier is insensitive to small signals immediately after reception of a large signal. A term describing the state of a semiconductor device or junction which eventually prevents the flow of current. / In network communications, a block is a fixed-size unit of data that is transferred together. For example, the Xmodem protocol transfers blocks of 128 bytes. / The process of fastening together two pieces of board by gluing blocks of wood in the interior angle. / In signal processing, group delay is a measure of the time delay of the amplitude envelopes of the various sinusoidal components of a signal through a device under test, and is a function of frequency for each component. Phase delay is similar, however it is a measure of the time delay of the phase as opposed to the time delay of the amplitude envelope. / state entered if a new user finds all channels or access mechanisms busy and hence is denied service. Generally accompanied by a busy signal. The call blocking probability may be given by the Erlang B or Erlang C formula. |
