ABSTRACT:
A level meter circuit for indicating a level of input signal over a wide dynamic range, comprising an amplifier of relatively high amplification factor having input terminal means to which an input signal is supplied and output terminal means to be connected to a level meter and negative feedback means including a feedback resistance to feedback an output signal from said output terminal means to said input terminal means, said negative feedback means characterized by further including non-linear impedance means connected in parallel to said feedback resistance and having such characteristics that when said output signal from said output terminal means is below a predetermined level said non-linear impedance means has a substantially infinite impedance and when said output signal from said output terminal means reaches said predetermined level said non-linear impedance means has a predetermined impedance.
