An analog front end circuit comprises a variable gain amplifier circuit (VGA circuit), a first sample switch, a second sample switch, a hold switch and an analog to digital converter device. The VGA circuit comprises a first input end, a second input end, and at least one output end. The...
Device for converting an analog signal into a digital signal of a parallel comparison type with error suppression circuits A device for converting an analog signal into a corresponding N-bit digital signal (A/D converter) of a parallel comparison type is disclosed having a 2.sup.N-M number ...
An integrator circuit comprises reset means (RST) by which when it is detected that an integrator output Vp for an input analog signal has coincided with a plus or minus reference value, the integral output is reset to the vicinity of the middle of the plus and minus reference values, in ...
A first analog input signal is converted into a plurality of second analog signals having different levels respectively. The second analog signals are inputted into respective analog-to-digital converters. Values of output signals from the respective converters are adjusted in accordance with the values...
A speech signal synthesizer features a time and frequency scaler for improved accuracy of signal synthesis. A digital signal representative of a first analog signal, such as a voice signal, having varying parameters, such as frequenty or amplitude, is converted by a synthesizer into an analog outp...
