Abstract (2. Language): 
Recently Analog to information convertors (AIC) have been introduces and an alternative for conventional ADCs in some especial applications. In this paper an Analog to information convertor namely RMPI, is practically implemented. The recovery has been carried out through Compressive Sensing (CS) recovery algorithms. Through employment of an Nyquist rate ADC and an Microcontroller, random samples where acquired from the signal. On average the sampling rate reduced to 10% to 50% of the Nyquist sampling rate. The recovered signal demonstrates to be comparable with Nyquist rate acquired signal in terms of quality and dynamic range. Application of the sampler in practical application like wireless sensor networks and Tele monitoring systems, brings about the advantage of efficient usage of bandwidth for data transmission and also reduction in power consumption on the sensor level.
