High speed IQ demodulation in FPGA – Ultrasound echo processing (some concepts)

I am building hardware for an ultrasound imaging system from scratch. The system overview and flow of ultrasound imaging will be explained soon in another post. Here I will explain a portion of the flow where analog-to-digital converted echo signals are poring into the FPGA (a typical echo signal looks as shown below). The signals… Read More High speed IQ demodulation in FPGA – Ultrasound echo processing (some concepts)

Is your laptop getting heated up ? WHY ??? What can be done ?

New laptops work fine, but as time passes heating problem starts. Especially when CPU usage by the software running in the laptop is more. Softwares  like MATLAB, Photoshop, Virus scanning softwares heat up the laptop. The reason for this increasing in temperature can be due to improper ventilation inside the laptop. Every laptop has an… Read More Is your laptop getting heated up ? WHY ??? What can be done ?
