Abstract: New designs of recursive wideband digital integrators are obtained by applying the zero-reflection approach over the existing recursive wideband digital integrators. The designed recursive digital integrators have all the poles and zeros inside the unit circle. These minimum phase integrator designs have highly improved linearity in phase responses as compared to the existing integrator designs. Therefore, the designed minimum phase recursive wideband digital integrators are more suitable for real-time control and signal processing applications.

Abstract: Human beings experience a non avoidable situation of sharing and posting their pictures, documents, videos etc on the internet almost every week. Intruders are often the ones who do not want to work hard and they claim on somebody's original work. Digital Watermarking has been an extraordinary rescue to the humiliating plight. There are broadly two most popular ways of embedding the watermark in the digital content ie spatial domain and transform domain. We present here the survey on both the kinds of methodologies in practice worldwide for authenticating images , in recent years.
