MOTOROLA K1T DRIVER

In the instant invention, however, the binary number signal outputs from the low pass digital filter 24 are sequentially fed to a logic circuit 50a, which has been designed to produce an activated output 51 for those combinations of input signals representative of a resultant tone amplitude above a selected threshold. The bandfass filter output is fed into an amplitude limiter, therefore the amount of passband ripple is not a critical parameter. Further, the carry output of each full and half adder , feeds to carry input of a subsequent adder. Noise which is coupled in through the transmission media is either im- pulsive or band limited gausskm white noise. Notes on Motorola V3xx plugin The V3xx plugin here listed should be valid for both Bluetooth and USB, but only one of them can be used with the same phone according to the way the device has been registered on the Mac, USB or Bluetooth. The function of the filter 24 is to strip the higher frequency undesired signals from the product detected output of the multipliers and to generate output signals in binary number form.

An isolation resistor placed in series with the hmiter input decreases the loading on the bandpass filter. This is an ampUtude measure- ment only, thus the period of the output is not critical.

For this reason, the optimum bandwidth is not determined according to motorolq data rate but rather according to achievable linear phase charac- teristics. The three most significant bits from the filter feed to a triplet of interconnected NAND gates which produce the logic output G 1.

The second harmonic Hzwhich is typically dB or more below the fundamental in amplitude, falls just outside the passband of the receive filter and is further attenuated.

Such items kt maximum input level and input offset voltage of the limiting device must be carefully considered. To further insure the proper detection of an input tone, threshold logic output 51 couples to the input of a second detector The Q output of the first four, second array, flip flops feeds to one input of corresponding full adders By superimposing circles of constant overdrive, those combinations of possible inputs Vo1, Vo2 having a given motoroola condition may be distinguished.

Thus, it is seen that using two delays 31, 35 allows low pass time multiplexing of both multiplier outputs. As a result of this procedure, at any point in time the output of the up-down counter indicates the number of 1’s in the shift register. Interface circuitry and system performance of the MC low-speed Modem.

The amount of modulation or sideband energy that falls in the adjacent channel is an item of concern in full duplex operation.

The test equipment was connected according to Figure Second detector 56 is comprised of a sample clock 58 which couples to one input of counting circuit 60, whose second input couples to the second detector input. Each step has been optimized such that the composite waveform has a maximum amount of signal energy at the fundamental.

In the present application, the required filter characteristic is a first order roll-off having a three db point at about 7. Thus, the figure shows as X’s those combinations representative of an overdrive less than 12 db. A time multiplexed digital low pass filter receives the mixer outputs removing all high frequency components.

I deleted everything which wasn’t a K1tt razor model, but left the “com. Moreover, the bandpass filter characteristics must be stable both as to temperature and time so as to assure proper operation of the communication system. How to use the plug-in, and related links. For this reason, the bandpass filter must have enough selectivity to reject the local carrier to an acceptable level.

Thanks for the glimmer of hope. The carry output of each half adder feeds to the input of a subsequent half adder.

These outputs, numbered in the drawing, are seen taken from the Q outputs of first array flip flopswhere they are fed to the threshold detector described more fully in FIG. The binary signals are passed to processing circuitry which has been preprogrammed to produce a first logic state output in response to combinations of binary signals which represent a resultant tone amplitude vector above a minimum threshold level. The A plugin here listed is valid for both Bluetooth and USB, but only one of them can be used with the same phone according to the way the device has been registered on the Mac, USB or Bluetooth.

A digital detector which detects the presence of a tone of a given frequency f in an incoming signal, having a reference signal generating means having a first and a second output, the first output producing a signal of frequency f at a first phase k1f, the second output producing a signal having a second phase reference in quadrature with the first phase reference; a first mixer for multiplying the reference signal generator first output and the input signal, a second mixer multiplying the reference signal generator second motorolaa and the input signal, the improvement comprising: In the third subsequent sampling time, motofola information stored in delay 35 is processed through multiplier 37, which as indicated above is here implemented by a shift and add routinewith the resultant summed in summer 29 along with clocked samples from the first multiplier.

The arrangement of claim 2 wherein the multiplexing means comprises a k1f switch operable at a predetermined rate to selectively couple the output from the first or second mixer to the digital filter first multiplier, and second time delay means comprising a flip flop register, said second time delay means having an input coupled to the digital filter time delay means output and an output coupled to the digital filter second multiplier input.
