Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
48 words
A wave translating circuit comprising capacitor means supplied with an input signal; limiter means for limiting the output of said capacitor means; and adder circuit means for adding the output of said limiter means to said input signal to produce an output signal from said wave translating circuit.
Claim 2
Dependent Claim
48 words
A wave translating circuit comprising capacitor means supplied with an input signal; limiter means for limiting the output of said capacitor means; and adder circuit means for adding the output of said limiter means to said input signal to produce an output signal from said wave translating circuit.
Claim 3
Dependent Claim
30 words
The wave translating circuit as claimed in claim 1, wherein said limiter means comprises a rectifier device connected between the output of said capacitor means and a predetermined potential point.
Claim 4
Dependent Claim
54 words
The wave translating circuit as claimed in either claim 1 or claim 2, wherein said adder circuit means comprises variable resistance means having input terminals coupled to the output of said limiter means and coupled to receive said input signal, respectively, and an output terminal coupled to the output of said wave translating means.
