Multi-Component Video System Controller

View page
US Patent:
44007353, Aug 23, 1983
Filed:
Jul 10, 1981
Appl. No.:
6/282305
Inventors:
Peter Strammello - Arlington Heights IL
Assignee:
Zenith Radio Corporation - Glenview IL
International Classification:
H04N 522
US Classification:
358181
Abstract:
Apparatus for simultaneously controlling the operating modes of a plurality of coupled video signal processing devices is disclosed. Manually operated pushbutton selectors provide D. C. control voltages to a plurality of electronic RF switches to permit the simultaneous viewing and recording of signals from various sources such as cable TV (CATV), subscription TV decoder (STV), video record (or disc) player, etc. , in any desired combination. Video signal losses due to signal splitting are avoided when viewing and recording the same input signal by means of unique cooperation between view and record manually operable selectors. Electronic diode switching circuitry controlled by a minimum number of user selectable inputs allows for a reduced number of controller components and simplified design while facilitating user operation.

Tunable Resonant Circuits For A Multi-Band Vhf/Uhf/Catv Tuner

View page
US Patent:
42715296, Jun 2, 1981
Filed:
Mar 20, 1980
Appl. No.:
6/132348
Inventors:
Peter Strammello - Arlington Heights IL
Assignee:
Zenith Radio Corporation - Glenview IL
International Classification:
H04B 116
US Classification:
455180
Abstract:
A conventional varactor tuned VHF/UHF television tuner with additional inductors placed in parallel in each VHF tuned circuit by means of diode switching provides an additional tuning capability over the CATV Superband. Selective tuning to any broadcast channel within the VHF, UHF and CATV bands is achieved by voltage-controlled tunable circuitry such as the type employing varactor diodes responsive to an adjustable DC tuning voltage having unique levels assigned to the various desired channels. By providing an additional bandswitching input voltage to a conventional tuner, Superband coils are diode-switched in parallel with VHF tuned circuits permitting an expanded tuning frequency range. This parallel coil approach in achieving Superband coverage permits the utilization of spring-wound VHF-band and Superband coils to facilitate tuning circuit alignment and to eliminate the need for a discrete Superband tuner or a CATV converter.

Image Trap Filter Circuit

View page
US Patent:
48356085, May 30, 1989
Filed:
May 31, 1988
Appl. No.:
7/200346
Inventors:
Mark J. Lachiw - Park Ridge IL
Peter Strammello - Arlington Heights IL
Assignee:
Zenith Electronics Corporation - Glenview IL
International Classification:
H04N 550
US Classification:
3581911
Abstract:
A varactor diode tuner includes a tunable image frequency trap in its input circuit. The trap is part of a tunable bandpass filter and forms a tapped capacitance matching network for UHF television signal carrier frequencies and a low impedance shunt at image frequencies. The trap is formed of discrete capacitors, an inductor and a tunable varactor diode.

Switching Diplexer For Single Antenna Input Television Receivers

View page
US Patent:
44994958, Feb 12, 1985
Filed:
Jul 26, 1982
Appl. No.:
6/401449
Inventors:
Peter Strammello - Arlington Heights IL
Assignee:
Zenith Electronics Corporation - Glenview IL
International Classification:
H04N 544
US Classification:
358188
Abstract:
The VHF and UHF tuners of a television receiver are coupled by a switchable diplexing circuit to a single antenna input terminal. The diplexing circuit includes a first electronic switching means responsive to a U/V bandswitch control signal connected between the UHF tuner and the antenna input terminal. A switchable low-pass filter is connected between the VHF tuner and the antenna input terminal, the switchable low-pass filter including a second electronic switching means responsive to the U/V bandswitch control signal for causing the low-pass filter to exhibit a first low-pass frequency response having a cut-off frequency fc in the VHF mode and a second low-pass frequency responsive having a cut-off frequency less then fc in the UHF mode.

Extended Range Tunable Resonant Circuit For A Vhf Television Receiver Tuning System

View page
US Patent:
44245947, Jan 3, 1984
Filed:
Oct 5, 1981
Appl. No.:
6/308018
Inventors:
Peter C. Skerlos - Arlington Heights IL
Peter Strammello - Arlington Heights IL
Assignee:
Zenith Radio Corporation - Glenview IL
International Classification:
H04B 126
US Classification:
455180
Abstract:
An extended range tunable resonant circuit for use in a VHF television receiver tuning system comprises a bandswitchable inductive network connected to a low series resistance gallium arsenide varactor diode. The resonant circuit, when operated in response to appropriate bandswitching signals and tuning voltages, is effective for establishing a plurality of tuning bands collectively defining an extended sub-UHF tuning range from about 54 MHz to at least 408 MHz.

All-Channel Television Tuning System

View page
US Patent:
45984255, Jul 1, 1986
Filed:
Feb 9, 1984
Appl. No.:
6/578462
Inventors:
Peter C. Skerlos - Arlington Heights IL
Peter Strammello - Arlington Heights IL
Assignee:
Zenith Electronics Corporation - Glenview IL
International Classification:
H04B 116
H03J 524
US Classification:
455180
Abstract:
An all-channel television tuner includes a single 75 ohm input for receiving airborne signals and CATV signals. A single band high frequency section tunes frequencies from 370 to 806 MHz and a three band low frequency section tunes frequencies from 54 MHz through 370 MHz. Both sections are coupled to the 75 ohm input through signal diverting means. A channel selector provides tuning voltages and band switching voltages to the sections and to the signal diverting means as a function of the channel selected.

Uhf/Vhf Splitter-Balun Assembly
