TUNER Assembly (AWZ1568)
NOTES:
• Parts without part number cannot be supplied.
• Parts marked by 'Cr are not always kept in stock. Their delivery time nay be longer than usual or they may be
unavailable.
• The th mark found on some component parts indicates the importance of the safety factor of the part. Therefore,
when replacing, be sure to use parts of identical designation.
• For your parts Stock Control, the fast moving items are indicated with the marks ** and 4c.
** GENERALLY MOVES FASTER THAN *
This classification shall be adjusted by each distributor because it depends on model number, temperature,
humidity, etc.
• When ordering resistors, first convert resistance values into code form as shown in the following exanples.
Ex.I When there are 2 effective digits (any digit apart from 0), such as 560 ohm and 47k ohm (tolerance is shown
by J=53, and K-107.).

11. CIRCUIT DESCRIPTION
11.1 New IF system principle
Fig.11-1 (a) shows the conventional IF system
which band is wide position, and Fig.11-1 (b)
shows the new IF system.
Vertical line indicates the time variable of
desired signal.
The line at right side of desired signal indicates
undesired signal.
Mountanious curve shows the amplitude
characteristic of IF filter.
In the case of conventional system, signal pass
through the filter without generate the distortion
so that filter is wide. At this time, the system
is affected by undesired signal.
In the case of new system, signal pass through
directly so that narrow filter follow the signal.
Besides, the system is not affected by undesired
signal.
This system's filter is controlled by feedforward
control, therefore, stability is very high and not
oscillation.
This system organize the equivalent follow type
filter so that input FM signal frequency
controlled for center of the filter at any time.
(At conventional system, filter is followed the
input signal.)
Fig.11-2 shows the block diagram. System is
consists of the control block and filter block.
Control block is consists of band pass filter
(19F1), FM detector (BET!) and low-pass filter
(LPF).
The band-pass filter (BPF1) has the same
characteristic as conventional tuner's narrow
filter, and this filter has selective
characteristic sufficiently.
When FA signal is inputed, FM signal is detected
by FM detector (DUI) after pass through the
band-pass filter (BPF1). And then, output signal
of FM detector (DET1) is cut the useless highfrequency elements by low-pass filter (LPF).
Filter block is consists of two mixer (MIX1 and 2).
band-pass filter (BPF2) and VCO.
Mixer 1 (MIX1) perform frequency change so that
multiply input FM signal by VCO output.
F-91 introduce the secondary IF frequency as 13.45
MHz.
Band-pass filter (BPF2) has the same narrow
bandwidth characteristic as the band-pass filter
(BPF1).
This filter (BPF2) cut the obstruction wave
including input signal.
Input signal of passed through the band-pass

frequency.
Original signal is detected by FM detector (DET2),
then audio output is obtained.
In this way, in spite of use the filter of fixed
the center frequency, F-91 operate to the

If desired signal (S) and undesired signal (U)

signals are appllied to control block, and cut
the undesired signal (U) by BPF1. At this time,
desired signal is distorted by BPFI.
This desired signal without undesired signal is
detected by FM detector (DET1), then changed the
FM waveform by VCO again.
Output signal of VCO is sum of the desired signal
(S) and the distortion element (D).
This distortion element (D) not only include
generated distortion at filter (BPF1) but also

include generated distortion at detector and VCO.

The differential element is took out from mixer 1

Then, desired signal (S) is obtained to not

NOTES:
• Parts without part number cannot be supplied.
• Parts marked by "0" are not always kept in stock Their delivery time may be longer than usual or they may be unavailable.
• The ii mark found on some component parts indicates the importance of the safety factor of the part. Therefore, when
replacing, be sure to use parts of identical designation.
• For your parts Stock Control, the fast moving items are indicated with the marks * * and *.
* * GENERALLY MOVES FASTER THAN*
This classification shall be adjusted by each distributor because it depends on model number, temperature, humidity, etc.
