ABSTRACT: The RF relay control‚ as the name suggests‚ operates at Radio Frequency. The corresponding frequency range varies between 30 kHz & 300 GHz. In this RF system‚ the digital data is represented as variations in the amplitude of carrier wave. This kind of modulation is known as Amplitude Shift Keying (ASK). Transmission through RF is better than IR (infrared) because of many reasons. Firstly‚ signals through RF can travel through larger distances making it suitable

SPA Lab 4: CONTRAST SENSITIVITY FUNCTION Ciara Dubose University of Central Oklahoma Abstract The purpose for this experiment is to determine at which spatial frequency does a participant’s visual acuity for a contrast sensitivity function display a peak performance across different sine – wave gratings. The ability to contrast sensitivity is useful in everyday life‚ more than people imagine. These contrast sensitivity functions focus primarily on the participants’ ability to detect accurately

design component over wide range of frequencies in a microwave receiver. The Broadband Amplifier design is to be done with Micro strip RF circuit design techniques and the required specifications are derived from the System level design. Therefore the system level design has to be done first. The Satellite Low Noise Block (LNB) is selected for system level design‚ which is one of the suitable applications for Broadband Amplifier. Receiving signal frequency is in

Unit 1 Problem Set 1 26. Surgery Versus Splints A study compared surgery and splinting for subjects suffering from carpal tunnel syndrome. It was found that among 73 patients treated with surgery‚ there was a 92% success rate. Among 83 patients treated with splints‚ there was a 72% success rate. Calculations using those results showed that if there really is no difference in success rates between surgery and splints‚ then there is about 1 chance in 1000 of getting success rates like the ones obtained

We will now generalize our discussion of transmission lines by considering EM waveguides. These are “pipes” that guide EM waves. Coaxial cables‚ hollow metal pipes‚ and fiber optical cables are all examples of waveguides. We will assume that the waveguide is invariant in the zdirection: y Metal walls b ‚ x z a and that the wave is propagating in z as e
