Изобретение относитс к автоматике и вычислительной технике и может быть использовано, в частности, в цифровых, анализаторах спектра дл логарифмического преобразовани аналоговых сигналов в двоичный код с заданньгм значением абсолютной погрешности во всем динамическом диапазоне изменени сигнала .The invention relates to automation and computer technology and can be used, in particular, in digital spectrum analyzers for the logarithmic conversion of analog signals to binary code with a given absolute error value over the entire dynamic range of a signal.
Известен способ логарифмического преобразовани напр жени в двоичный код, основанный на том, что под воздействием входного сигнала формируют экспоненциально спадающее напр жение, которое затем сравнивают с р Дом пороговых напр жений. Временной интервал от начала исследовани процесса до момента сравнени с м порогом анализируют и формируют двоичный код, соответствующий логарифму входного сигнала l1.There is a known method of logarithmic transformation of voltage into a binary code, based on the fact that, under the influence of an input signal, an exponentially decaying voltage is formed, which is then compared with p Home of threshold voltages. The time interval from the beginning of the process investigation to the moment of comparison with m threshold is analyzed and a binary code is formed corresponding to the logarithm of the input signal l1.
Известен также способ логарифмического преобразовани аналоговых величин в двоичный код, основанный на формиро-There is also known a method of logarithmic conversion of analog values into binary code, based on
вании измен ющегос напр жени н подсчете , начина с некоторого фиксированного момента времени и до момента вре мени совпадени линейно измен ющегос напр жени и входного напр жени , импульсов , частота следовани которых обратно пропорциональна входному сигналу 2,the variable voltage on the counting, starting from a certain fixed point in time and until the time of coincidence of the linear variable voltage and the input voltage, of the pulses, the frequency of which is inversely proportional to the input signal 2,
Известные способы преобразовани позвол ют формировать двоичный код с Known conversion methods allow generating a binary code with
10 посто нной относительной погрешностью преобразовани и не позвол ет обеспе .чить во всем динамическом диапазоне Изменени входных сигналов посто нство абсолютной погрешности преобразовани .10 constant relative error of conversion and does not allow to ensure constant absolute conversion error over the entire dynamic range of the Change of input signals.
