Title: Effective-value measuring device
Inventor: RONARUDO ERU SUWAAREIN
IPC: G01R19/25
Filed: 1992-06-05
Abstract: PURPOSE: To provide an RMS value voltmeter with a high measuring precision which can be manufactured at low cost. CONSTITUTION: A signal to be measured is coupled to a first RMS converter 4 having a good high frequency response and a short time constant by way of an input coupling network 3. An output of the first RMS converter is digitized by an A/D converter and is processed by a second RMS converter 5. The time constant of the second RMS converter 5 is set to a length enough to measure a ripple frequency from the first RMS converter 4 which is merely several Hz. The second RMS converter 5 may be provided with a preference filter which compensates for an attenuation of an input signal to be measured which is caused by a DC block in the input coupling network. A third RMS converter 10 is coupled to the output of the first RMS converter 4 and is used for controlling an automatic range switching logic.

Title: Privacy call system
Inventor: TAKAHARA MASAHIRO
IPC: H04W12/02
Filed: 1987-07-09
Abstract: PURPOSE:To improve the flexibility of the system and to make it impossible to manufacture an interception equipment by generating a digital privacy voice signal from a digital voice signal by a digital privacy call circuit. CONSTITUTION:A mobile body scrambler (MSCR)3 applies signal processing by an incoming digital voice signal outputted from an AD conversion section COD 2 and a digital privacy call pattern signal supplied from a mobile body privacy call control section (MSCTL) to generate an incoming digital privacy call signal. The digital privacy call signal is converted into an incoming analog privacy call signal by a DA converter (DEC) 4. In this case the MSCR3 generates an incoming digital privacy call signal from the incoming digital voice signal and the digital privacy call pattern signal and its content is a signal not discriminated by ears of a person in converted into an analog signal. Thus, the conversion from the digital voice signal into the digital privacy call signal is selected at random even time privacy control is applied corresponding to the call. Thus, the flexible system is attained and the manufacture of interception equipment is made difficult.
