the basic issue in this article is to analyze the relationships of characters in nezami’s khosrow & shirin by using of greimas’s actors pattern. in nezami’s narrative we found the six actors that greimas mentioned; including: transmitter, recipient, subject, object, helper, and deterrent. according to the results of this article the transmitter is part of khosrow’s character – his unconsciousne...

The opener-stretcher motor neuron in crayfish makes 50 endings upon each of 1200 muscle fibers. We have calculated the quantal content of junctional potentials produced by individual terminals and by the whole cell at various physiological frequencies. The results show that when the motor neuron is active at 20 impulses/second, it releases 50 quanta/impulse per muscle fiber, or a total of 4.5 x...

The TekExpress USB-RMT software enables flexible and intuitive receiver margin testing of USB 3.0 designs with the AWG7000 series Arbitrary Waveform Generators. The BERTScope BSAUSB31 Automated USB 3.1 Receiver Solution is desig...

This paper describes the architecture and operation of a direct conversion transmitter for integration with the Bioluminescent Bioreporter Integrated Circuit (BBIC). The transmitter circuit is designed for 916 MHz frequencies. This system is made up of Phase Lock Loop (PLL), Gilbert Cell mixer, Power Amplifier and Antenna. The power amplifier is added to transmit the data in desired distance. S...

Multiple-input–multiple-output (MIMO) systems have the potential to achieve very high capacities, depending on the propagation environment. Capacity increases as signal correlation decreases. We present the measurements of a MIMO system under strong and weak line-of-sight conditions. The system capacity decreases as the distance from the transmitter increases. Indeed the transmitter correlation...

This letter presents a new design method of a low-power transmitter for inductive link. The proposed method introduces the concept of class-F RF amplifiers into an inductive data link. The power dissipation of the class-F transmitter is analyzed for carrier and symbol transition. It is revealed that the proposed transmitter consumes extremely low power of less than 0.2 nJ/bit with BPSK modulati...

We study the asymptotic capacity of MIMO wireless channels predicated on channel knowledge (or channel state information CSI) at the transmitter in the high SNR regime. The transmitter CSI studied includes instantaneous and transmit correlation types. The receiver is assumed to know the channel perfectly. Analytical expressions for the asymptotic ergodic capacity are derived in each case, which...

Here we propose a current mode oscillator circuit using Q-Dot technology and subsequently we modify this circuit for transmitter and receiver design. We like to note that transmitter is a amplitude modulation (AM) to frequency modulation (FM) conversion technique. The receiver is of Super heterodyne structure, where the RF front end is implemented by Q-Dot devices and the IF stages are implemen...

As part of a multi-channel, multi-band evaluation platform for future wireless sensor network applications, an IEEE 802.15.4a standard conform transmitter is investigated. The paper gives an overview of our transmitter concept and ultra-wide band signals according to IEEE 802.15.4a. It analyzes the system design aspects of the transmitter for high flexibility such as modularity and independency...
