In between the electronics described above and the digital volume control is the dreaded CMOS switch matrix that selects the DAC out, the eight-channel analog input, or the stereo analog signal direct from the analog switch
matrix for direct mode.
Designed to operate from a single 1.8 V to 5.5 V power supply, the analog switch
conducts audio signals in both directions with very low distortion.
Traditional electrical systems have long been designed around a series of analog switches
connected to a power source.
With low RDS(on), low threshold voltage, and 1.5-V gate drive capability, these new MOSFETs are positioned as suited for smallsignal load switches, analog switches
, and high-speed interfacing.
The 570A's test library includes all common analog ICs including op-amps, comparators, voltage regulators, voltage references, analog switches
and multiplexes, opto-isolators and couplers, and audio ICs.
For example, analog switches
in the NEATSwitch range include the world's smallest 16-pin SMD quad-SPDT (single-pole, double throw) switch in a 2.6 x 1.8 x 0.55mm QFN16 package and the smallest dual-SPDT switch, housed in a 2.5 x 1.3 x 0.7mm DFN10 package.
Intended for staffed datacenters, the analog switches
are available in 8- and 16-port versions, and can be connected in a tiered fashion to increase server access from eight to as many as 128 servers (256 servers when tiering to an HP IP Console Switch).
Future plans include installing AMX analog switches
that will connect to servers in the Austin Envisioning Center--a studio for customer presentations that will feature the latest Windows 2003 server operating systems.
Variables in Z include: ([Z.sub.1]) total demand, measured as the local service revenue in the state; ([Z.sub.2]) the percent of total, analog switched
access lines serving residential customers; ([Z.sub.3]) a dummy for New York and Texas, both leading states in the promotion of competition; ([Z.sub.4]) a dummy variable if the incumbent is allowed to provide interLATA long distance (AR, KS, MA, MO, NY, OK, PA, and TX); ([Z.sub.5]) a dummy variable if the installation charge to competitors for the element combination exceeds $50; and ([Z.sub.6]) a dummy variable for the independent variable's date (0 for June 2001 and 1 for December 2001).
The injection of foreign capital has allowed the company to replace old analog switches
with modern digital ones.
