The emitter coupled pair of BJT’s gives a linear transfer relation between the differential output voltage and the differential input voltage V_id only. When the magnitude of V_id is less than '$$\alpha$$' times the thermal voltage, where '$$\alpha$$' is

Compression in PCM refers to relative compression of

For a given data rate, the bandwidth B_p of a BPSK signal and the band width B₀ of the OOK signal are related as

Quadrature multiplexing is
