Wideband Voltage Doubling Detector with Improved Sensitivity
Abstract: The voltage doubling detector can be used to improve sensitivity in field strength meters, RF sniffers, Tuned Radio Frequency receivers and wireless power harvesting. To further boost the detector’s sensitivity, we utilize broadband transformers to efficiently transfer energy between antenna and detector. This paper presents three wideband transformers that can improve voltage sensitivity up to 6.5 times.

Design of Digital Frequency Sensitive Phase Detector and study its Phase Response
Abstract: In this paper, a digital frequency sensitive phase detector (PD) with voltage controlled phase response is presented. This scheme is based on classical type flip-flop phase detectors and an improved PD operating on both edges of the input sequence. Phase-to-voltage response characteristic control is accomplished by the additional feedback of the low-pass filter output voltage to reset the control pin input. In this paper, we have presented a simulated frequency …

Estimation of JPEG Image Compression for Colour Images Using the Forensic Detector
Abstract: Multimedia items would be required to transmit the secret information between the sender and recipient in order to raise the security level imposed on them. Watermarking is the most frequently habituated system for adding security to photos. In numerous cases, using a watermarking strategy to give security isn't feasible. Because the security communication is visible, hackers may add a watermark on the original image, just like the sender did, and …

Series Resistor Method for Higher Signal-to-Noise Ratio and High Sensitivity in Superconducting Nanowire Single-Photon Detectors
Abstract: A series resistor method has been presented for higher signal-to-noise and high sensitivity in superconducting nanowire single-photon detectors (SNSPD). This method has given a very high useful data yields exceeding 50% while still maintaining pure single-photon operation and wide dynamic range. The SNSPD signal is roughly proportional to the nanowire width, so narrow nanowire have poor signal-to-noise ratio (SNR) at widths from 4–30 nm and fabrication at these length scales …
