Signal measuring apparatus of digital many power consuming one ASIC designed and made
Summary : Originally design as a multi-functional digital measuring apparatus, measure frequency range measure for 64Hz periodicity of 1Mz fix the signal Frequency , cycle , peak value , average of voltage and peak of voltage (such as sinusoidal wave , triangular wave , ladder wave , sawtooth wave , pulse signal , oblique wave ,etc. ).
System adopt ultrafast video glimmer A/D converter to to examine signal carry on datum of voltage sample two passway; Adopt two group LED display realize and person who examines signal and display of project to result; Adopt FPGA to make central processing unit, realize the facelift of the signal to examining by way of pure software, finish frequency , data processing of cycle , average of voltage , voltage peak peak value and and communication of keyboard , display , A/D converter.
