We present a reconfigurable acquisition and wavelet-based detection circuit, NeuroBetaMed, for in vitro biological signals. It is implemented on a configurable digital integrated circuit (FPGA). We consider real-time computing as a hard specification and silicon area as a price to pay. It is designed for noisy signals like those recorded from in vitro cellular preparations, by extracellular electrodes. NeuroBetaMed performs biological signal acquisition, stationary wavelet transform (SWT) and
