Title: Echo suppressor
IPC: H04B3/20
Filed: 1978-11-23
Abstract: To detect the condition under which break-in occurs in an echo suppressor, the signal in the send path is compared with a threshold representing the highest peak that has occurred in the signal in the receive path during the preceding time T where T is not less than the maximum end delay suffered by an echo returning from receive path to end path. A number N of registers R1 to RN are provided. The peak signal in the receive path is derived in each register in turn during N successive periods of time t2, the value so derived remaining unchanged for time t1 = (N - 1) t2 until the cycle is complete. The output threshold is the maximum of the values in all N registers and for any peak the prolongation time T is such that t1 < T < t1 + t2. <IMAGE>

Filed: 1979-08-08
Abstract: A hot-electron or hot-hole transistor includes a base region (2) through which hot majority charge carriers (7) flow. The application of a bias voltage (VBE) is necessary to supply such carriers (7) having energies above the base-collector barrier, thus improving the collection efficiency. The emitter-base barrier- forming means comprises a semiconductor barrier region (4) having a sufficiently large thickness and impurity concentration of the opposite conductivity type to the base region that said barrier region (4) is only partially depleted by the depletion layer or layers present at the emitter-base barrier at zero bias. The hot majority carriers (7) can be produced by punch-through of the depletion layer(s). The emitter may comprise a Schottky contact (5) or an ohmic contact. Low emitter capacitance can be obtained by including a lower-doped zone (6) of either conductivity type to extend the emitter-base depletion layer(s). In another form (see Figures 7 and 8) the emitter-base barrier forming means also includes an insulating layer (14). The base-collector barrier can be formed by a fully depleted barrier region (1). <IMAGE>
