    • A Radio Frequency Identification (RFID) reader according to one embodiment of the invention includes a first microprocessor acting as a controller, and a second microprocessor, e.g., DSP, in communication with the first microprocessor, the second microprocessor generating a digitally synthesized waveform. A converter converts the digitally synthesized waveform to an analog waveform. A modulator combines the analog waveform with a carrier signal for generating an outgoing signal. The waveform may have rising and falling edges of varying shape. A RFID reader in another embodiment includes an amplifier for amplifying an incoming RF signal, a switchable filter receiving an amplified signal from the amplifier, and mixers receiving a filtered signal from the filter. An RFID reader in another embodiment has adaptive carrier cancellation. A circuit for amplitude modulating a carrier signal is presented. Methods are also presented.

    • A method of testing a device includes monitoring an output of the device, wherein the output is generated by the device in response to an applied test command; and resolving the output into atomic operations, wherein the atomic operations are substantially the smallest constituent operations which are substantially independent of the device. The method is used to provide a simple, comprehensive test environment that effectively test 1394a and 1394-1995 designs, for example, in Verilog. The test environment contains rules which completely characterize the behavior of different 1394 bus protocols as defined by the IEEE specifications. The test environment provides portability between different devices under test and between different protocols, automated closed-loop reconciliation of test commands and protocol requirements, topology independence, and out-of-order execution of instructions or relative sequencing. The test environment further allows failure injection, and separate and independent design of the device and a test system.
    • 测试设备的方法包括监视设备的输出,其中输出由设备响应于所应用的测试命令而生成; 并将输出解析为原子操作,其中原子操作实质上是基本上独立于设备的最小成分操作。 该方法用于提供一个简单,全面的测试环境,有效测试1394a和1394-1995设计,例如Verilog。 测试环境包含完整描述IEEE规范定义的不同1394总线协议行为的规则。 测试环境提供了不同被测设备之间以及不同协议之间的可移植性,测试命令和协议要求的自动闭环协调,拓扑独立性以及指令或相对排序的乱序执行。 测试环境还允许故障注入,以及设备和测试系统的独立和独立设计。
